    　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.

    　View Summary

    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.

  • Dielectric elastomer actuators using Slide-Ring Material (R) with increased permittivity

    Shigeki Tsuchitani, Tokiharu Sunahara, Hirofumi Miki

    SMART MATERIALS AND STRUCTURES ( IOP PUBLISHING LTD )  24 ( 6 )   2015.06  [Refereed]

    　View Summary

    The inclusion of high permittivity nanoparticles in elastomeric materials for dielectric elastomer actuators (DEAs) is one promising method to achieve large strain at relatively low applied voltages. However, the addition of these nanoparticles tends to increase the stiffness of the elastomer and disturbs the actuation of the DEA. This is attributed to restriction of the chain motion in the elastomer by the nanoparticles. Slide-Ring Material (R) (SRM) is a cross-linked polymeric material with freely movable cross-linking sites. The internal stresses in this structure are dramatically homogenized by the pulley effect; therefore, the restriction of chain motion due to the nanoparticles is expected to be significantly reduced. We have employed SRM as a host elastomer for a DEA with the addition of ferroelectric BaTiO3 (BT) nanoparticles. The effects of BT addition on the permittivity, stiffness and viscosity of the SRM-BT nanocomposites, and the actuation strain of DEAs using SRM were evaluated. The permittivity of the nanocomposites increased linearly with the concentration of BT and reached 3.6 times that for pure SRM at 50 wt%. The elastic modulus and the viscosity remained almost constant up to 20 wt% and then decreased above this concentration. The actuation strain of a planar actuator using SRM and 50 wt% BT was four times larger than that of the DEA with pure SRM.

  • Fabrication of microstructure array directly on beta-phase poly(vinylidene fluoride) thin film by O-2 reactive ion etching

    Hirofumi Miki, G. Matsui, M. Kanda, S. Tsuchitani

    JOURNAL OF MICROMECHANICS AND MICROENGINEERING ( IOP PUBLISHING LTD )  25 ( 3 )   2015.03  [Refereed]

    　View Summary

    The ability to pattern a thin film of poly(vinylidene fluoride) (PVDF), a piezoelectric, pyroelectric and ferroelectric polymer, has potential applications in the fields of microelectromechanical systems (MEMS), nonlinear optics and nonvolatile ferroelectric random access memory technology. Low pressure O-2 reactive ion etching (RIE) was employed to realize fine pitch microstructures on a beta-phase PVDF (beta-PVDF) film for the first time; a line and space (70/130 mu m) microstructure array with a height of over 30 mu m was fabricated. Different to the traditional method of PDMS molding, the proposed technology did not result in significant loss of piezoelectricity. Furthermore, unlike the x-ray photo-etching method, there was no etching saturation limit with the proposed method. Here, we introduce the fabrication process technology in detail and report on the etching properties of the beta-PVDF film under different process conditions. The effect of process variables, such as supplied gas flow, applied RF power and etch time, on the PVDF etching characteristics were investigated in detail. The RF power and etch time showed a more predominant influence on PVDF etching progress than the gas flow. The etched depth was linearly increased with the etch time and the amount of RF power. Etching rates over 10 mu m h(-1) were achieved and increased linearly with the applied RF power. By means of a responding photomask design and control of process conditions, much finer and higher microstructure arrays are also possible.

    　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.

    　View Summary

    We report a method of fabricating microstructures directly on a thin beta-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 degrees C per 4 h. The constant of d(33) in the range above 60 degrees C per 4 h linearly deteriorated with the rise in temperature by 0.3 x 10(-12) (C N-1) degrees C-1 and at a temperature of 100 degrees C per 4 h; deterioration of about 50% was confirmed. The N,N'-dimethyl acetamide (DMA: C4H9NO) solution was used as the etchant for wet etching, and O-2 plasma 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.

  • Thermal characterization of micro heater arrays on a polyimide film substrate for fingerprint sensing applications

    J Han, Z Tan, K Sato, M Shikida

    JOURNAL OF MICROMECHANICS AND MICROENGINEERING ( IOP PUBLISHING LTD )  15 ( 2 ) 282 - 289   2005.02

    　View Summary

    A new type of micro fingerprint sensor was proposed and the sensing principle was demonstrated using micro heaters as the sensing elements. The arrayed sensing elements were micro resistors made of sputtered 200 nm thick platinum film on a 50 1,mum thick flexible polyimide film substrate. The temperature coefficient of resistance was 0.0029 (K-1) and showed good linearity. Because of the small thermal capacity and effective thermal isolation, the resistance of the heater showed high sensitivity and short response time to the applied power. By applying a pulsed voltage of 5.4 V at ambient air, the heater temperature could be increased from room temperature to 300 degreesC in 0. 1 mus. When a fingerprint model (line and space: 100 mum; pattern height: 50 mum) made of silicone rubber was in contact with the sensor surface, contacting patterns of the fingerprint model were clearly recognized as the difference in resistance, i.e. in temperature. Micro through-holes with a diameter of 90 mum were wet etched vertically on the polyimide film substrate. The sensor array on the front surface and the wiring on the rear surface of the substrate were interconnected by depositing I mum thick copper film inside the through-holes using the electroless plating technique. The whole fabrication processes were simple and achieved in a low temperature range (< 130degreesC ) on the non-silicon, low-cost and flexible substrate.

    　View Summary

    We have presented the characteristics of polyimide (PI) film wet-etching using the commercially available and most commonly used Kapton Upilex PI-film as the testing materials and a strong alkaline solution named TPE3000 (from Toray Engineering Co., Ltd., Japan) as the etchant. We have introduced the fabrication process of micro through-holes on the PI-film by wet-etching using two types of etching-mask materials, i.e. a photosensitive dry film and thin copper film. We have also developed thermal-type micro sensor device using densely arrayed micro heaters as the sensing elements. The sensing elements were resistors made of sputtered 200-nm-thick platinum film on the thin (50-μ m-thick) flexible PI-film substrate. The electrical feed-through was arranged on the different sides of the substrate and interconnected to the micro heater elements via the wet-etched through-holes, inside walls of which were deposited with thin metal film by means of the electroless copper plating technology. The fabricated device was robust, flexible and can be attached to non-flat curved surface. © 2005, The Institute of Electrical Engineers of Japan. All rights reserved.

  • Three-dimensional interconnect technology on a flexible polyimide film

    JS Han, ZY Tan, K Sato, M Shikida

    JOURNAL OF MICROMECHANICS AND MICROENGINEERING ( IOP PUBLISHING LTD )  14 ( 1 ) 38 - 48   2004.01

    　View Summary

    We present polyimide (PI) film wet-etching technology, and a cost-effective fabrication process of three-dimensional interconnects on the thin flexible PI film. Densely arrayed micro through-holes (diameter < 100 mum) on the flexible PI film were fabricated by wet-etching technology, and three-dimensional metal interconnects were formed by the electroless Cu plating process. We have also proposed and fabricated a vertically interconnected high-density micro thermal sensor array directly on the 50 mum thick Kapton PI film, and we have performed some experiments. Sensor elements (0.1 mum thick nickel film; upper side of the PI film formed by vacuum evaporating) and electrical feed-through (1 mum thick Cu film; back side of the PI film formed by electroless Cu plating) were vertically interconnected by electroless Cu plating via the wet-etched micro through-holes. The evaporated nickel film showed good adhesion to the PI film without any pre-treatment, and its temperature coefficient of resistance was about 2600 ppm. The poor adhesion of plated Cu to the PI film surface could be improved by PI film wet treatment with a strong alkaline solution TPE3000. In the proposed sensor device, the sensing elements showed very fast thermal response and good thermal isolation from the substrate, due to its small thermal capacity and Kapton PI film inherent characteristics of excellent thermal isolation (lambda = 0.12 W/(m degreesC)).

    SENSORS AND ACTUATORS A-PHYSICAL ( ELSEVIER SCIENCE SA )  100 ( 1 ) 114 - 122   2002.08

    　View Summary

    We are developing a fingerprint-sensor device that has one-dimensionally arrayed high-density microheater elements. To provide thermal isolation, we designed and fabricated two sets of insulation cavities for the heater elements, one to reduce the heat transferring from the heater elements to the substrate and the other one to reduce that of heat to the wiring. The insulation cavities in the first set are etched and laterally penetrate under the heater bridges, leaving a SiO2 diaphragm with the heater bridges on it. Those in the second set are etched lengthwise of each heater element, leaving a set of SiO2-wiring bridges over them. These SiO2-wiring bridges are used to perform metal-film wiring. The wiring (an electrical feed through) is formed using the lift-off method and running on the SiO2, film surface from the heater element to the bonding pad through the SiO2-wiring bridges; in this way, the amount of heat transferred to the wiring is reduced. The fabricated sensor device was made on a (1 0 0) silicon-on-insulator (SOI) wafer using micromachining technology. Each heater bridge was 5 mum x 17 mum x 50 mum with a pitch of 80 mum. Because of its small thermal capacity and effective thermal isolation, the sensor element is very sensitive. When a 0.4 V/20 mus pulse voltage was applied to the heater elements, their resistance reached a steady maximum value in about 4-5 mus, i.e. the temperature rise was saturated promptly.

    　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.

    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.

    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.

    　View Summary

    We proposed an ultra-thin structure of thermal-type micro sensor array having excellent thermal isolation and sensitivity by using 25similar to50-mum-thick polyimide (PI) film as the substrate. The device also has the attractive features of mechanical flexibility allowing three-dimensional packaging. For vertical interconnects, microvia holes (diameter <100mum) were made by PI film wet etching. Arrayed heater elements with 0.1-mum-thick nickel film were formed by using lift-off technology, and electrical feed-through with 2-mum-thick Cu film were formed by electroless Cu-plating. Heater elements (front side) and electrical feed-through (backside) were interconnected through the fabricated microvia holes using electroless Cu-plating. Fabricated heater elements (Ni) showed good adhesion with the PI film substrate, and its temperature coefficient of resistance (TCR) was 2600ppm. Because of the small thermal capacity and good thermal isolation, the sensor also showed high thermal response of less than 0.4mus when 280mV/10mus of pulse voltage was applied to the heater elements.

    　View Summary

    We describe the structure and fabrication of a one-dimensionally arrayed high density thermal-type micro fingerprint sensor. To provide thermal isolation, we designed and fabricated two sets of insulation cavities for each heater element, one for reducing the heat-transfer from the heater to the substrate, and the other one for that of heat to the wiring. The first set of cavities were etched under each heater bridge, leaving an SiO2 diaphragm with the heater bridge on it, and laterally penetrating with the cavities of neighboring heater bridges. The second ones were etched at the both ends of each heater element, leaving a set of SiO2-wiring bridges. This SiO2-wiring bridge structure was used as a thermal isolator when performing a metal-film wiring. The wiring (an electrical feed-through) was formed by a lift-off method, and runs on the SiO2 insulation surface from the heater element to the bonding pad through the SiO2-wiring bridges. The fabricated sensor device was made on a (100) SOI (silicon-on-insulator) wafer. Each heater element was 5x17x50 ( mum(3)) with a pitch of 80 gm. Because of its small thermal capacity and effective thermal isolation, the sensor element was very sensitive. When a 0.4-V/20-mus pulse-voltage was applied to the heater elements, their resistance reached a steady maximum value in about 4similar to5 p. This level of sensitivity will be useful in variety of thermal sensors, such as micro temperature sensors and micro flow sensors, in addition to the thermal-type fingerprint sensors.

    「永久磁石を使ってものを動かす」というテーマで、青少年のための科学の祭典に展示のため、数ヶ月前から準備をし、子供達に理科・科学に対する関心・感動を高めようと努力した。(水を入れた細長い水路の両脇に電極を付けて電流を流し、水路の下に磁石を置く。磁石と水は引き付けあったり反発しあったりしませんが、水は磁界から力を受けてある方向に流れ始める),日付:2009.11

    小・中・高校生を対象とした学部体験入学・出張講座等

    「電磁石で音を出す」電磁石に電流を流すと、磁石と同じように目には見えない磁力線が出て鉄板を引き付けます。この電流を変化させると磁力線の数が変化するので引き付ける力が変化し、音の電流を流すと、鉄板でできたもの(缶やバケツなど)が振動してスピーカのように音を出します。普通、アルミや銅は磁石に引き付けられませんが特殊な電流を流すと鉄板と同じく音を出すことを実演展示しました。(小・中学・高校生500),日付:2008.10

    「めっきで絵を描こう」金属は水にはほとんど溶けないが、特殊な状態では溶けることができる。溶けた金属はイオン状態になって独特の色を表し、金属の溶けた液はまるで色の付いた透明な水に見える。この液の金属イオンをほかのものの表面にくっつけることを「めっき」という。赤色の銅板にマジックで絵をかき、その上にめっきするとマジックで書いたところめっきが乗らない。この現象を利用して同じ金属の色違いを見せてもらう。,日付:2007.10～2007.9
