Electric field control of propulsion force of a boat driven by chemical Marangoni effect

Shigeki Tsuchitani, Takumi Ikebe, Hirofumi Miki, Kunitomo Kikuchi

Colloids and Surfaces A: Physicochemical and Engineering Aspects 592 2020.05 [Refereed]

　View Summary

© 2020 Elsevier B.V. Chemical Marangoni propulsion (CMP) is a driving on fluid by surface tension imbalance around object caused by anisotropic distribution of surfactant or by the reaction of Marangoni convection caused by the surface tension gradient. The purpose of the study is a remote control of the propulsion force in CMP. Electrostatic interaction of ionic surfactants as propellant with external electric field (EF) is expected to modify the surfactant distribution and modulate the surface tension gradient. We selected surface active imidazolium-based ionic liquids (ILs) as propellants. Effects of the application of the EF (667 kV/m) to the IL layer emitted from the object on the propulsion force and the accompanying Marangoni convection were evaluated on aqueous surface. When hydrophobic ILs with [PF6] anion were used, the application of the EF decreased the propulsion force and also decreased the flow velocity and flow width of Marangoni convection. The decreasing rate of the propulsion force increased with the alkyl-chain length of the IL cations. The maximum decreasing rate was 33 %. We considered that the main reason for the EF-induced reduction in the propulsion force is the decrease in the surface tension gradient due to the increases in the surface tension of the emitted IL layers caused by the rearrangement of the surface active IL molecules on aqueous surface. This is the first report about the EF control of the propulsion force in CMP.

Unstable Spreading of Ionic Liquids on an Aqueous Substrate

Langmuir ( AMER CHEMICAL SOC ) 33 ( 41 ) 11040 - 11046 2017.10 [Refereed]

　View Summary

© 2017 American Chemical Society. The spontaneous spreading of thin liquid films over substrate surfaces is attracting much attention due to its broad applications. Under particular conditions, surfactants deposited on substrates exhibit unstable spreading. In spite of the large effects of the stability of the spreading on the accuracy and efficiency of industrial processes that use the spreading, understanding how the stability of the spreading process is governed by the physical and chemical properties of the system is still little known. Recently, ionic liquids have been characterized as a new kind of surfactant due to their special properties. Here, we investigate the stability of the spreading of deposited imidazolium-based ionic liquids on an aqueous substrate. We focus mainly on the effects that the water solubility of the ionic liquids has on the stability. Hydrophobic ionic liquids exhibit spreading that has a highly periodic and petal-like unstable spreading front, whereas hydrophilic ionic liquids spread without such a regular spreading front and their spreading area shrinks after reaching its maximum. We propose a model for the generation of unstable spreading of hydrophobic ionic liquids, i.e., the unstable spreading front is created by the penetration of oncoming water in front of the spreading tip into the more viscous spreading ionic liquid layer, like the viscous fingering that occurs in a Hele-Shaw cell. However, the direction of the penetration is the opposite of the direction that the interface moves (the spreading direction), which is contrary to that in viscous fingering.

Study of the influence of the hydration level on the electromechanical behavior of nafion based ionomeric polymer-metal composites actuators

Laos Alexandre Hirano, Lenin Wagner Acerbi, Kunitomo Kikuchi, Shigeki Tsuchitani, Carlos Henrique Scuracchio

Materials Research ( UNIV FED SAO CARLOS, DEPT ENGENHARIA MATERIALS ) 18 154 - 158 2015.12 [Refereed]

　View Summary

The ionomeric electroactive polymers-metal composites (IPMC) are materials that realize bending movements in response to an electrical stimulus and can be applied to the artificial muscles development. This paper investigated the influence of the hydration level on the electromechanical behavior of Nafion based IPMC. An experimental apparatus composed by a system to measure the bending force and to control the electrical stimulus and the relative humidity around the sample was developed. The main results indicated that samples with higher hydration level produce larger bending forces, but they show a more expressive back relaxation with lower time constant. A discussion about the results considering some models described in the literature conclude the paper.

IEEJ Transactions on Electrical and Electronic Engineering ( WILEY-BLACKWELL ) 9 ( 5 ) 572 - 574 2014.09 [Refereed]

　View Summary

A novel method for fabricating a miniaturized ionic polymer-metal composite (IPMC) with plated gold electrodes is developed by combining selective plasma irradiation and electroless plating. The membrane is irradiated by SF6 or CF4 plasmas through a stencil mask prior to plating to prevent deposition of a gold electrode in the plasma-irradiated area. Miniaturized IPMCs are fabricated with a 400-μm-wide line-and-space pattern. The proposed method has the potential to realize miniaturized IPMCs combined with microelectromechanical system (MEMS) devices because this provides a direct and simple fabrication process. © 2014 Institute of Electrical Engineers of Japan.

Chemical propulsion using ionic liquids

Shigeki Tsuchitani, Nobuhiro Takagi, Kunitomo Kikuchi, Hirobumi Miki

Langmuir ( AMER CHEMICAL SOC ) 29 ( 9 ) 2799 - 2804 2013.03 [Refereed]

　View Summary

Chemical propulsion generates motion by directly converting locally stored chemical energy into mechanical energy. Here, we describe chemically driven autonomous motion generated by using imidazolium-based ionic liquids on a water surface. From measurements of the driving force of a locomotor loaded with an ionic liquid and observations of convection on the water surface originating from the ionic liquid container of the locomotor, the driving mechanism of the motion is found to be due to the Marangoni effect that arises from the anisotropic distribution of ionic liquids on the water surface. The maximum driving force and the force-generation duration are determined by the surface activity of the ionic liquid and the solubility of the ionic liquid in water, respectively. Because of the special properties of ionic liquids, a chemical locomotor driven by ionic liquids is promising for realizing autonomous micromachines and nanomachines that are safe and environmentally friendly. © 2013 American Chemical Society.

Microstructure fabrication on a β-phase PVDF film by wet and dry etching technology

Journal of Micromechanics and Microengineering 22 ( 8 ) 2012.08 [Refereed]

　View Summary

We report a method of fabricating microstructures directly on a thin β-phase polyvinylidene fluoride (PVDF) film without losing much of its piezoelectricity by employing wet and dry etching technologies. The piezoelectricity of PVDF depends greatly on the temperature, as is generally known. The process conditions, including the PVDF temperature history, were evaluated in experiments where there was almost no change in the PVDF film piezoelectric constant below 60°C per 4h. The constant of d 33in the range above 60°C per 4h linearly deteriorated with the rise in temperature by 0.3×10 -12(C N -1) °C -1and at a temperature of 100°C per 4h; deterioration of about 50% was confirmed. The N,N′-dimethyl acetamide (DMA: C 4H 9NO) solution was used as the etchant for wet etching, and O 2plasma was used for the reactive ion etching (RIE). Tens to a hundred micrometer microstructures were easily fabricated with the proposed approach. The fabrication process technology and experimental results are also reported in detail. © 2012 IOP Publishing Ltd.

Comparative study of bending characteristics of ionic polymer actuators containing ionic liquids for modeling actuation

Journal of Applied Physics ( AMER INST PHYSICS ) 109 ( 7 ) 2011.04 [Refereed]

　View Summary

Ionic polymer metal composites (IPMCs) that can operate in air have recently been developed by incorporating an ionic liquid in ionic polymers. To understand transduction in these composites, it is important to determine the role of the ionic liquid in the ionic polymer (Nafion®), to identify the counter cation, and to investigate the interaction of IPMCs with water vapor in the air. We used Fourier-transform infrared spectroscopy to analyze three Nafion® membranes, which were soaked in mixtures of water and an ionic liquid (1-ethyl-3-methyl-imidazolium tetrafluoroborate (EMIBF4), 1-buthyl-3-methyl-imidazolium tetrafluoroborate (BMIBF 4), and 1-buthyl-3-methyl-imidazolium hexafluorophosphate (BMIPF 6)). The results demonstrate that only cations (EMI+ and BMI+) in the ionic liquids are taken into the Nafion® membranes as counter ions and that the water content of the membranes in air is less than ∼4% that of Nafion® swollen with water. Based on the experimental results, a transduction model is proposed for an IPMC with an ionic liquid. In this model, bending is caused by local swelling due to the volume effect of the bulky counter cations. This model can explain 30-50 of the experimentally observed bending curvature. © 2011 American Institute of Physics.

Nafion®-based polymer actuators with ionic liquids as solvent incorporated at room temperature

Kunitomo Kikuchi, Shigeki Tsuchitani

Journal of Applied Physics ( AMER INST PHYSICS ) 106 ( 5 ) 2009 [Refereed]

　View Summary

Nafion®-based ionic polymer-metal composites (IPMCs), with ionic liquids as solvent, were fabricated by exchanging counterions to ionic liquids at room temperature. Ion exchange is performed by only immersing IPMC in a mixture of de-ionized water and ionic liquids at room temperature for 48 h. The fabricated IPMCs exhibited a bending curvature the same as or larger than that of conventional IPMCs with ionic liquids, formed by ion exchange to ionic liquids at an elevated temperature up to about 100 °C, and also had long-term stability in operation in air, with a fluctuation smaller than 21% in bending curvature during a 180 min operation. The effective ion exchange to ionic liquids in the present method is probably due to an increase in diffusion speed of ionic liquids into IPMC by adsorption of water in a Nafion® membrane. It is a surprise that among IPMCs with ionic liquids 1-ethyl-3-methyl-imidazolium tetrafluoroborate, 1-buthyl-3-methyl-imidazolium tetrafluoroborate (BMIBF4), and 1-buthyl-3-methyl-imidazolium hexafluorophosphate (BMIPF6), IPMC with water-insoluble BMIPF 6 exhibited a larger bending curvature than that IPMC with water-miscible BMIBF4. This might be due to effective incorporation of BMIPF6 into IPMC, since BMIPF6 has a higher affinity with IPMC than with water in the mixture of water and BMIPF6. From measurements of complex impedance and step voltage response of the driving current of IPMCs with ionic liquid, they are expressed by an equivalent circuit of a parallel combination of a serial circuit of membrane resistance of Nafion® and electric double layer capacitance at metal electrodes, with membrane capacitance of Nafion®, in a frequency range higher than about 0.1 Hz. The difference in magnitude of bending curvature in three kinds of IPMCs with ionic liquids is mainly due to the difference in bending response speed coming from the difference in the membrane resistance. © 2009 American Institute of Physics.

Formation of patterned electrode on solid polymer electrolyte using photolithography technique

Seimitsu Kogaku Kaishi/Journal of the Japan Society for Precision Engineering ( The Japan Society for Precision Engineering ) 74 ( 7 ) 719 - 723 2008.07 [Refereed]

　View Summary

An Ionic Polymer-Metal Composite (IPMC) consists of a thin ionomeric membrane with noble metal electrodes formed on both surfaces. IPMCs have a potential as soft robotic actuators and artificial muscles with several advantages such as flexibility, light weight, and low driving voltages. Highly durable IPMCs will be fabricated using an electroless chemical plating technique to form metal electrodes. In this study, a fabrication method for patterning electrodes with a size of several micrometers has been developed to realize IPMCs, which will be capable of a peristaltic movement. A selective electroless gold plating and an epoxy-resin based photoresist are applied for patterning electrodes. By using a photomask with a pattern-size of 50 um, patterned electrodes are formed on an ionomer (Nafion) membrane, resulting in the size of 65 urn. This pattern size is much smaller than that in conventional patterning methods using a selective electroless plating technique and masking tapes or stencil masks. The sheet resistance of the fabricated electrodes is lower than 30 fl/o, which is almost same order of magnitude as that of electrodes formed by the conventional electroless plating without photolithography.

Inner Structure / Elastic Modulus Control of Micro Cantilever

Journal of the Japanese Society for Experimental Mechanics ( The Japanese Society for Experimental Mechanics ) 8 94 - 97 2008.06

　View Summary

It is important to know mechanical properties of micro structures fabricated as a micro machine component by micro-stereolithography (μSL). In the previous study, we reported that elastic modulus of a micro-cantilever fabricated by μSL is controllable by irradiation laser power and postcure processing time. In this study, micro-cantilevers are formed by changing lamination pitch (10 μm to 25 μm) and lamination orientation. Then, the relation between the load and the deflection of the cantilever is evaluated. Experimental results show that the elastic modulus of the cantilever decreases with the increase of the lamination pitch.

Kikuchi Kunitomo, Miwa Masafumi, Tsuchitani Shigeki

Abstracts of ATEM : International Conference on Advanced Technology in Experimental Mechanics : Asian Conference on Experimental Mechanics ( The Japan Society of Mechanical Engineers ) 2007 ( 6 ) "OS16 - 4-1-1"-"OS16-4-1-5" 2007.09

　View Summary

We are developing novel variable-focal length lenses using IPMC. In this paper, we propose the structure of the novel variable-focal length lens using IPMC and describe the results of the experiment for the principle verification of the lens. The relation between generated force of IPMC and focal length of the proposed lens was modeled. Moreover, the possibility of the proposed variable-focal length lens was confirmed, since the basic operation is verified by using liquid as a lens material.

　View Summary

In order to drive the micro robot which we developing using IPMC as a propellant actuator effectively, it is necessary to clarify abilities of IPMC such as displacement and generation force. Since ability of IPMC is greatly influenced by species of counter ion (movable ion that is responsible for bending of IPMC). Then, in this research, we evaluated displacement characteristics and generation force of IPMC when the counter ion was changed. As a result, displacement of IPMC including Ca^<2+> or K^+ as counter ion, was larger by 1.7 times compared with that including Na^+. Moreover, the generation force was larger by 2.3 times in the case of Ca^<2+> and by 1.8 times in the case of K^+, compared with the case of Na^+. As a result, it was confirmed that the performance of IPMC changed greatly with the counter ion.

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) 2019 The Japan Society of Mechanical Engineers

　View Summary

In this paper, we present a power assist suit that supports and transports heavy objects with a single motor. The leg mechanism of the power assist suit is made of upper and lower parallel links and springs. It is designed to be located inside the wearer's legs so that the power assist suit becomes small and light-weight, and the stability during transportation is improved. We measured the surface electromyogram (EMG) during luggage lifting experiments and confirmed that the burden of the wearer's back and legs is reduced when wearing the developed power assist suit.
Development of a gripper for power assist suits with a ratchet mechanism consisting of linear motion and rotational motion parts

HORIGUCHI Koki, OGAWARA Koichi, SUZUKI Arata, KIKUCHI Kunitomo

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) 2019 The Japan Society of Mechanical Engineers

　View Summary

L-shaped grippers typically used for power assist suits have a problem in stably holding objects of arbitrary shape. To solve this problem, we developed a gripper with a ratchet mechanism consisting of linear motion and rotational motion parts. The gripper can be deformed according to the shape of the wearer's hand and the shape of the object to be held, and the shape of the gripper can be fixed due to the rachet mechanism, thus objects of arbitrary shape can be held stably by this gripper and the burden of the wearers is reduced. We carried out experiments where four types of objects were held by the developed gripper. We showed that the developed gripper has reduced the wearer's burden for two types of objects among four.

　View Summary

In this paper, we present a mechanical design of a wire drive mechanism for power assist suits that realizes linear luggage lifting movement and nonlinear knee fixation-and-release movement using a motor. The nonlinear fixation-and-release movement is realized by a mechanism using a piston and a crankshaft. We developed an algorithm to find the design parameters that minimize the error from the optimal wire movement. We developed a prototype wire drive mechanism and verified that it works as designed. In addition, we carried out lifting experiments and confirmed that luggage up to 20 kg can be lifted. We measured the surface electromyogram (EMG) and confirmed that the burden of the wearer's arms was reduced during luggage lifting.

Evaluation of Operation Characteristics of Ionic Polymer-Metal Composite as a Self-Sensing Actuator with Variable Electrode Pattern

UCHIDA Shusaku, KIKUCHI Kunitomo

The Proceedings of Mechanical Engineering Congress, Japan 2018 The Japan Society of Mechanical Engineers

　View Summary

Ionic polymer-metal composite (IPMC) is one of the most promising soft actuators for practical applications of medical and welfare devices. Also, IPMC can work as a self-sensing actuator because it is a kind of smart material which can generate voltage by its deformation. In this study, effects of separated electrodes at three different sizes on operation characteristics of sensing outputs of self-sensing IPMCs are evaluated with applying a driving voltage to the actuator part. The self-sensing IPMCs have three separated electrodes formed by a machining process which work as an actuator part, a sensor part and a shield part, respectively. In the evaluation, a bridge circuit is used because the outputs of the sensor parts are small. As a result, the sensing outputs can be seen in the IPMC with the smallest cutting grooves because the length and width of the sensor affects the sensor outputs. Moreover, it is confirmed that larger cutting groove can decrease noise from the driving voltage for the actuator part in the sensor outputs. It is suggested that the width and length of separated electrodes of the self-sensing IPMC are important to operate as the self-sensing actuator.
Evaluation of Driving Characteristics of a Nylon Actuator Driven with PEDOT:PSS Heater

The Proceedings of Mechanical Engineering Congress, Japan 2018 The Japan Society of Mechanical Engineers

　View Summary

In this study, we propose a novel coiled thermoplastic polymer actuator with a conductive polymer heater made of PEDOT:PSS. Also, the driving characteristics of the proposed actuator are evaluated. As a result, it was confirmed that the actuator was able to be driven by applying a low voltage with contraction ratios (5.0[%]) as same as those in the previous studies with applying 5.0 [V]. In addition, we evaluate driving characteristics of the actuators fabricated by our proposed method with a hydrophilic treatment and fixing process in the coling. The actuator with the hydrophilic treatment can operate with smaller differences of contraction ratios of the each actuator than that without the treatment. Also, the response speed of the actuator with fixing process in the coling is improved by 12.6[%] compared to that without the process. It is suggested that these improvements are provideed by good conductivity of PEDOT:PSS fabricated by the proposed method because the length of the actuator is variable to provide PEDOTPSS enogh thickness during membrane production. As a conclusion, it is confirmed that the proposed method has a posibility to improve the driving characterisitics of the thermoplastic polymer actuator.

　View Summary

In this study, we propose a DEA with conductive polymer electrodes made of PEDOT:PSS-PG because conventional dielectric elastomer actuators use conductive greases or metals for electrode and difficult to drive stably due to their stiffness and deformation. The proposed DEA consists of polymer materials fully. From the characteristics evaluations, the proposed DEA can exhibit 7.3[%] maximum area strain at 5.6[kV]. It drives stably because the dielectric breakdown strength is almost constant in different samples. Also, PEDOT:PSS electrodes have a possibility to be used as transparent electrodes. As these results, the proposed DEA will be helpful to improve driving characteristics of DEA.
Evaluation of Driving Characteristics of Ionic Polymer-Metal Composite Actuators Driven by PWM Control Method

FUKUI Ryuichi, KIKUCHI Kunitomo

The Proceedings of Mechanical Engineering Congress, Japan 2018 The Japan Society of Mechanical Engineers

　View Summary

Ionic polymer-metal composite (IPMC) is one of the most promising soft actuators. IPMC is expected to be applied to medical devices such as microgrippers for cells because of its high biocompatibility. However, there are some big problems to be solved in IPMC when IPMC work in practical applications including micro grippers. For example, it is difficult to miniaturize the control devices with IPMC. Also, IPMC usually have a back-relaxation after initial large deformation. In this study, we propose a pulse width modulation (PWM) driving method by using a single board computer to make IPMC drive stably with low back-relaxation. In order to achieve our purpose of this study, we designed a driving circuit and evaluated the operation characteristics of the IPMC driven by the proposed method. As a result, the displacement of IPMC is greatly displaced during the first about 5 seconds in the proposed method. However, it is found that the displacement stabilized without back-relaxation compared with the case using the potentiostat. As a conclusion, it is confirmed that the proposed method is useful for IPMC with stable driving.

　View Summary

Thermoplastic polymer actuators have attracted attentions because of their generation force ( > 10[MPa]), low weight, low cost and reversible contraction ( >10[%]). Nylon actuators are one of the most promising thermoplastic polymer actuators. Therefore, many researchers and engineers have been researching them to apply them to a soft actuator for soft robotics. There are two kinds of Nylon actuator. One is super coiled type actuator such as over-twisted type and mandrill type. The other is sheet type. In this study, a finite element method (FEM) model with a simple structure model for super coiled type Nylon actuator is proposed as an initial stage. This model has a possibility to make it easier to physics based analysis with material properties changed. Mechanical properties of Nylon were taken into consideration for a simple helical structure. In this model, a torque and angle of twist to relax torsion of actuator were applied to a cross section of Nylon fiber to imitate actuator motion caused by heating. As a result, it was confirmed that total length of Nylon actuator contracted with the angle of twist increasing.

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) 2016 The Japan Society of Mechanical Engineers

　View Summary

Ionic Polymer-Metal composite (IPMC) sensor is one of the most promising polymer deformation sensor to realize a type of self-sensing actuator. In this research effect of input state on outputs of IPMC sensor is evaluated with three alkali metals (Li+, Na+, K+). As a result, it is suggested that the larger Stokes radius of cation in IPMC improve the sensors outputs. Also, it is thought that the response speed of IPMC sensor is limited due to its stiffness and movement of cation because rapid deformation blocks to generate electric potential difference between cations and anions.

MORIOKA Daichi, KIKUCHI Kunitomo, NAKAGAWA Yuki, ISHIHARA Daichi

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) 2015 The Japan Society of Mechanical Engineers

　View Summary

We propose the fabrication process of an IPMC-based soft gripper using a plasma process which is one of the most general MEMS technologies. This method enables the fabrication of the soft gripper from a sheet of IPMC. Also, this gripper can operate in solution. As a result, the operation of the gripper fabricated by the proposed process in solution was confirmed. In order to evaluate the usability of the gripper, the bending performance and the generative force under a constant voltage appliance were measured respectively. From the results, the soft gripper was able to grab a small sample, whose diameter and weigh are 1.0 mm and 12 mg, when 3.5 V was applied in DI water. These results show a feasibility of providing a miniaturized soft gripper using IPMC which has a novel structure

ISHIHARA Daichi, KIKUCHI Kunitomo

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) 2015 The Japan Society of Mechanical Engineers

　View Summary

This paper describes an evaluation study on frequency characteristics of Ionic polymer-metal composite (IPMC) sensors with Li^+ and Na^+. IPMC was composed of Nafion N117 as an ion exchange membrane and 5times gold plating electrode. To understand the time-domain frequency characteristics of the sensors, the sensor signals were evaluated by wavelet analysis method in air. As a result, the signals with Na^+ was larger than those with Li^+. It is indicated that the IPMC sensor with smaller cations has a kind of noise-reduction effect more effectively than that with the large cations because the size of cation affected the driving characteristics of the IPMC sensors.

　View Summary

Friction and wear arise in contact sliding parts of machines, increases in wear and deformation of the sliding parts caused by frictional heat. Induce mechanical failure lubricants are used to prevent these problems, but lubricant is evaporated or decomposed by frictional heat. In recent years, ionic liquids are attracting much attention as new lubricants. Ionic liquids have various non-conventional physical and chemical characteristics. We used three types of imidazolium ionic liquids: BMI-PF_6 (1-Butyl-3-methylimidazolium hexafluorophosphate), HMI-PF_6 (1-Hexyl-3-methylimidazolium hexafluorophosphate), OMI-PF_6 (1-Octyl-3-methylimidazolium hexafluorophosphate) with different alkyl chain length. They were coated on Si substrates with SiO_2 layer on the surface. We measured frictional force between the substrate coated with the ionic liquid and AFM (atomic force microscope) conductive tip as voltages were applied between them. It was confirmed that frictional force increased by applying voltages. The sample coated with HMI-PF_6 exhibited the largest increase in frictional force when voltages are applied.

By realizing micro self-moving bodies which don't need energy supply from the outside and one equipped with a power source, applications of them to environmental sensing device, and transportation equipments of small objects on water surface, are possible. Since it has been reported that the self-motion on water surface in possible by using an ionic liquid [BMIM][PF_6] (1-butyl-3-methylimidazolium hexafluorophosphate) an a fuel which causes surface tension gradient on water surface and generate propulsion force, we focused on self-motion using ionic liquids. To establish method to control driving force, driving time and moving direction of this micro self-motion mechanism powered by ionic liquids. We measured driving force of a locomotion which has a nozzle to report ionic liquid on water surface and evaluated effects of the shape of the nozzle.

　View Summary

Recentlt, self-motion is attracting attentions as a new motion mechanism that does not require energy supply from outside. Micro self-motion mechanism, in expected to be applied to transportations of small bodies in the water and environmental sensing devices. Among them, driving method using surface tension gradient on water surface are known. By using ionic liquids with ampliphilic chemical structure which can modify surface tention of water surface, the object can be driven by converting chemical energy into mechanical energy directly. We already, confirmed that small objects depositing an imidazolium-based ionic liquid [bmim][PF_6] (1-butyl-3-methylimidaz-olium hexafluorophosphate) moved spontaneously on water surface. In this study, by using a magnetic ionic liquid [bmim][FeCl_4](1-buthyl-3-methylimidazoium Tetrachloroferrate) containing a magnetic anion, we examined a potential application to control the direction of the self-motion by applying magnetic field.

　View Summary

Recently, as a new motion mechanism, the self-motion mechanism has attracted attention. By realizing micro self-motion mechanism being not required energy supply from the outside and equipped with a power source, the application in the water is expected to environmental sensing device, transport of small objects and so on. Self-motion mechanism uses the surface tension of water (cohesive force of water), and it is the mechanism to convert chemical energy to mechanical energy directly. However in the water, since the effect of viscous resistance is increased by reducing the moving body, it is required for self-motion mechanism that energy sources to generate the movement of high efficiency, large driving force, and long time. Then, since it has been reported that the self-motion of the object by attaching the ionic liquid [BMIM][PF_6] (1-butyl-3-methylimidazolium hexafluorophosphate) on the water, we focused on self-motion using ionic liquids. Thus, we intended to establish a method to control micro self-motion mechanism powered by ionic liquids. In this study, we measured the surface tension and observed the Spreading by using four ionic liquids.

Thermal-magnetic inkjet mechanism for the application of micro pattern fabrication on the highly unlevel microarea

2012 International Symposium on Micro-NanoMechatronics and Human Science, MHS 2012 2012

　View Summary

We proposed a novel type of inkjet mechanism (thermal-magnetic driving) employing the magnetic material Curie temperature. In the magnetic circuit composed of N-S of magnet poles, the magnetizing field through temperature-sensitive magnetic fluid inside the circuit will show no-gradient uniform vector field. When the temperature-sensitive magnetic fluid inside the circuit was getting a rapid temperature rise locally, its magnetization will disappear locally, so that results in a precipitous magnetic gradient and pumping force (Maxwell stress). There, the moving elements like piezo-plates are absolutely unnecessary, and a high temperature rise like in the thermal bubble type inkjet is also not necessary. By employing a low Curie-temperature magnetic fluid (Ferrite or FeNiCr nanoparticle), it is possible to generate enough of ejecting power at 50-120°C. In the proposed inkjet system, magnetic fluid ink was used to alleviate the bursting phenomenon of the ink-drop and enlarge the flying distance of ink-drop. The pumping power was realized by the Maxwell stress generated from the precipitous magnetic gradient of the magnetic fluid in the inkjet head. The working mechanism was verified by the analysis software COMSOL MULTIPHYSICS simulation and the optimal structure was analyzed. The fabrication process was also discussed. The detailed simulation results will be presented in the conference presentation. © 2012 IEEE.

　View Summary

Ionic polymer-metal composite (IPMC) is one of the most attractive soft actuators because it have several unique characteristics such as low driving voltage and large strain. Therefore, it allows the material to fulfill specific needs for medical device applications. IPMC consists of a polyelectrolyte membrane and thin noble metal electrodes formed on the both surfaces of the membrane. By fabricating IPMC with patterned electrodes, it will be capable of complex motions such as peristaltic movement. In spite of numerous challenges in order to utilize IPMC in medical devices, there are many technological subjects to fabricate it. Conventionally, the most reliable formation method is a chemical gold plating method. For this reason, we already developed a formation method of patterned electrode using photolithography techniques and the chemical plating method. However, in this method, the side wall of the IPMC was also plated when it was not covered by the photo resist, and the both electrodes are short-circuited. To solve this problem, we developed a new formation method of patterned electrode using SF6 plasma treatment. In this method, during the plating, the electrode cannot be formed on the SF6 plasma-irradiated areas of the membrane probably by decreasing of ion-exchange group due to fluorine termination process to the polymer chains. Therefore, the cutting process of the side wall does not need, and this method can be easily incorporated with micro machining technologies.

　View Summary

Ionic polymer metal composite (IPMC) is a very attracting soft actuator having large strain under low application voltage. It consists of an ionic polymer membrane and thin electrodes formed on the both sides of the membrane. By applying voltage in water, it bends by movement of hydrated counter ions and accompanying electroosmotic water flow. We fabricated Flemion-based IPMCs by incorporating ionic liquids (EMIBF4, BMIBF4, BMIPF6) exchanging counter ion, and also an IPMC with Li as counter ion. Various heights of step voltages (0.5 to 2.0V) were applied to the IPMCs in water, andresponses of bending curvature and driving current were measured. Effects of the kind of the ionic liquid and the voltage height on the responses were evaluated. The responses of bending curvature 1/R and electric charge Q transferred by counter ion, which was obtained by integrating the driving current, were well corresponded, and seemed to consist of two stages%3b the first is accumulation process of counter ion to the electrical double layer between the electrode and the ionic polymer with response times less than 5s, and the second stage is slower process longer than 10min. 1/R - Qcurves tended to saturate with increase in the charge Q in the IPMCs including the ionic liquids, though the IPMC with Li had no such tendency. This saturation is considered to arise from the water flow of the opposite direction to that of the movement of the counter ion due to pressure gradient in the IPMCs.

　View Summary

Much research has focused on producing actively controllable tip catheter for more minimally invasive intravascular treatment. In this work, we designed 4-electrode type active micro catheter using polypyrrole (PPy). We used SEPLEGYDA [○!R]for a seed layer in electrochemical deposition of PPy. SEPLEGYDA[○!R] is low hardness and easy to form a conducting layer compared to metal electrode layer. As a result of a finite element analysis, 4-electrode type active micro catheter achieved the minimum radius of curvature of 16.4mm which is sufficient for intravascular treatment. To realize 4-electrode type active micro catheter, we fabricated unimorph (1-electrode) type active micro catheter to establish a basic fabrication technologies. When a step voltage of 1.0V was applied to the PPy in a NaCl solution, the catheter bent with a radius of curvature of 580mm.

　View Summary

Polymer actuators are attracting considerable interest due to their special characteristics, including high flexibility and low weight. Ionic polymer-metal composite (IPMC) are polymer actuators that exhibit remarkable bending at driving voltages lower than 2 or 3 V. They have the potential to be used as soft robotic actuators. IPMC consists of a thin ion-exchange membrane with noble metal electrodes formed on both surfaces. Highly durable IPMCs will be fabricated using an electroless chemical plating technique to form metal electrodes. In this research, we have been developed a fabrication method of IPMC with patterned electrode which will be capable of a peristaltic movement. In this paper, we describe a fabrication method for patterning electrodes by the electroless chemical plating technique with SF_6 plasma treatment and the results of performance evaluation of IPMC with SF_6 plasma treatment.

　View Summary

In this paper, we proposed a structure of an active catheter using polypyrrole (PPy). PPy is one of conducting polymer actuators that are suitable for microactuator for medical use. We fabricated an active catheter of two actuator type which was coated with an electrolyte gel. It was driven in air, and a radius of curvature of 146mm was obtained. In order to enlarge the bending displacement of the catheter, we used thin metal films as electrode for polymerization of PPy. A trimorph actuator with an Au electrode and an electrolyte gel to drive PPy in air, exhibited 6.4 times larger curvature than that using a conducting polymer as electrode. We simulated the operation of the active catheter with the Au electrode to optimize various sizes by a finite element analysis. © 2011 IEEE.

Proceedings of the International Conference on Sensing Technology, ICST 2011

　View Summary

This paper provide a novel and potential method to realize a flexible and high sensitive, high resolution skin sensor useful for the application of robotic skin. MEMS technology was applied and by etching process 140∼300/40- μm of micro structures were realized easily directly on the elongated and polarized polyvinylidene fluoride (β - PVDF) film that will be used as the sensing element in the skin sensor. The effects of PVDF film etching condition, especially the experienced temperature history to the PVDF important sensing parameter of piezoelectric constant was evaluated by experiment. PVDF film etching characteristics were introduced also. N,N′-dimethyl acetamide (DMA, C 4H 9NO) solution was used as the wet etching etchant, and O 2 gas for the RIE dry etching process. Under the temperature of less than 55°C , the PVDF film piezoelectric constant was got almost no change, and at the range over 55°C , the constant start to deteriorate linearly according with the temperature rise about 0.3×10 -12; (C/N)/°C. At about 100°C , there was only 50% of deterioration on the PVDF film piezoelectric constant. Such a strong piezoelectric activity will be useful to the sensitivity of the skin sensor. By photo mask design and control of the process condition, much fine and complex micro structure could be fabricated directly on the PVDF film without noticeable degradation of its piezoelectric constant, and it will be useful to realize the required soft and high sensitive, high-resolution skin sensor. © 2011 IEEE.

In this study, in order to develop fabrication process of ionic polymer-metal composite (IPMC) actuator of microcantilever type, we evaluated actuation characteristics of a thin film type IPMC. Though its displacement was smaller than that of IPMCs fabricated by using the commercial ionic polymer (Nafion) film, the actuation of the thin film type IPMCs was confirmed. It depended on the thickness of the Nafion layer. We can expect the realization of MEMS devices integrated with the thin film type micro IPMCs fabricated by the propose method. ©2010 IEEE.

　View Summary

In this study, electrical properties of ionic polymer-metal composite (IPMC) with an ionic liquid (IL) as a solvent, were evaluated in air. 1-ethyl-3-methyl-imidazolium tetrafluoroborate (EMIBF4) was used as an IL. As a first approximation for the initial several seconds after application of the step voltage (0.5 or 1.5V), IPMC was explained by a simple equivalent circuit model expressed as a serial combination of the membrane resistor and the electrical double layer capacitor. The membrane resistance decreased with increasing environmental humidity. On the other hand, as for the double layer capacitance, at the lowest humidity of 20%RH, it was almost same between the two different voltages. In addition, the estimated membrane resistance agreed relatively well with the resistance of this equivalent circuit expressed as a parallel combination of a resistor and a capacitor which was derived from the complex impedance measurement in the frequencies higher than 5.0Hz. © 2009 SICE.

Basic technologies to realize an active micro catheter using polypyrrole (PPy) as an actuator are being developed. The catheter is composed of a resin tube, a thin metal film for polymerization of PPy, and a PPy deposited on the electrode. From a finite element analysis, it was proved that a silicone tube with a diameter of 0.5mm and a thickness of 0.05mm is the best for our specification. Copper film for electropolymerizing PPy, was deposited by RF sputtering on the silicone tube. The copper film was patterned by a laser machining. PPy was polymerized on the copper film, which was deposited on the half side of the silicone tube. When a voltage of 1.5V was applied to the PPy vs. a titanium electrode in a NaCl solution, the tube bent with a radius of curvature of 12cm. © 2009 SICE.

Recently, the miniaturization of the industrial product is remarkable, and it is predicted that further miniaturization is realized. And, a manipulator which handles those miniaturized industrial products is also desired to be miniaturized small size. In this study, the development of micro gripper fabricated by micro-stereolithography (μ SL) was done. Using micro-stereolithography, elastic modulus of the specific portion of a fabricated minute structure was controlled by changing some fabrication conditions. And test micro gripper with controlled elastic modulus of joint part was developed. The control method of elastic modulus was realized by changing the intensity of the curing laser light and lamination pitch of photopolymer resin.

We fabricated a liquid lens type variable-focal length lens(VFLL), which is composed of a container with a movable silicon plate having a pupil (diameter: 4mm) covered by a thin polydimethylsiloxane (PDMS) film, a liquid enclosed in the container and a plural IPMCs fixed above the container for pushing the silicon plate downward. By applying a force to the silicon plate by IPMCs, the PDMS film of the pupil deforms upward. As a result, the focal length of the liquid lens decreases. The proposed method for fabricating VFLL has a large potential to realized very small VFLL. © 2009 SICE.

　View Summary

Operating characteristics of ionic polymer-metal composite (IPMC) using ionic liquids (ILs) as solvent were measured in air. Among three kinds of IL (1-ethyl-3-methyl-imidazolium tetrafluoroborate (EMIBF4), l-buthyl-3-methyl-imidazolium tetrafluoroborate (BMIBF4), and 1-buthyl-3-methyl-imidazolium hexafluorophosphate (BMlPF6)), IPMC using BMIPF6 exhibited the largest curvature of 3.3 m1 under an application of a rectangular wave voltage (±2.0V) with a frequency of 0.5Hz. It was found that the behavior of IPMC using ILs changed depending on environmental humidity. The maximum curvature during the voltage application, and the initial response speed of curvature were larger with increasing environmental humidity and voltage height. Time dependence of the curvature well corresponds to that of the transported charge due to movement of counter ions. Therefore, it is possible to explain the curvature response by the behavior of the transported charge. © 2009 Materials Research Society.

Materials Research Society Symposium Proceedings 2008.09 MATERIALS RESEARCH SOCIETY

　View Summary

Conjugated polymers such as polypyrrole and polyaniline, have excellent features as actuator, such as flexibility, light weight and large deformation under low application voltage. We fabricated a bilayer microactuator of two kinds of polypyrrole (PPy) films doped with two different dopants, i.e., dodecylbenzene sulfonate (DBS -) and p-phenol sulfonate (PPS -), on a silicon substrate using micromachining technology and electrochemical deposition of PPy. The fabricated actuators was 0.5mm long, 0.2mm wide and 1μm thick. In the fabrication of the microactuator, PPy(PPS) and PPy(DBS) were successively deposited on a patterned Au electrode, a part of which adhered to the silicon substrate through an adhesion layer of Cr. The fabricated microactuator was actuated in an aqueous solution of sodium hexafluorophosphate (1mol/l) by applying a voltage of +0.7V to PPys versus a counter electrode (Pt). In the first voltage application, the Au layer underneath the PPy layers peeled away from the silicon substrate except the contacting part with the Cr layer and bent about 90 degree in about 18s, since adhesion force between Au and Si is enough smaller than that between Au and Cr. After the second voltage application, the microactuator bent stably having a response speed of about 5s. © 2009 Materials Research Society.

Proceedings of the SICE Annual Conference 2008 IEEE

　View Summary

Nafion®-based ionic polymer-metal composites (IPMCs), whose counter ions are exchanged using ionic liquids, are fabricated. EMIBF4, BMIBF4, and BMIPF6 are used as ionic liquids. During long-term (180min.) operation in air, changes in curvature of IPMCs are about 10% of the initial one. This change is enough smaller than that of conventional IPMCs using metallic counter ion. The curvature is larger in IPMC having lower charge transfer resistance, which is evaluated measuring frequency dependent complex impedance of IPMC. Furthermore, charge transfer resistance of IPMC decreases with increase in environmental humidity. © 2008 SICE.

　View Summary

Nafion®-based ionic polymer-metal composites (IPMCs), whose counter ions are exchanged using ionic liquids, are fabricated. EMIBF4, BMIBF4, and BMIPF6 are used as ionic liquids. During long-term (180min.) operation in air, changes in curvature of IPMCs are about 10% of the initial one. This change is enough smaller than that of conventional IPMCs using metallic counter ion. The curvature is larger in IPMC having lower charge transfer resistance, which is evaluated measuring frequency dependent complex impedance of IPMC. Furthermore, charge transfer resistance of IPMC decreases with increase in environmental humidity. © 2008 SICE.
