3. Fujio TSUMORI, Akinori SAIJOU, Toshiko Osada, Hideshi Miura, Development of actuation system for artificial cilia with magnetic elastomer, Japanese Journal of Applied Physics, 10.7567/JJAP.54.06FP12, 54, 6S1, 06FP12-1-06FP12-5, 2015.05, In this paper, we describe the development of magnetically actuated artificial cilia. Natural cilia are a highly efficient device that produces flow under a small-Reynolds-number state. There are two important characteristics of natural cilia; one is asymmetric movement, which is composed of effective and recovery strokes, and the other is the phase difference of a stroke in each cilium in an array that will produce a metachronal wave. In this paper, we propose an actuation system for artificial cilia composed of a silicone elastomer and multiparticle chains of a magnetic material. The applied magnetic field is controlled by rotation of a permanent magnet. This rotating magnetic field induced an asymmetric movement similar to that of a natural cilium. We also changed the orientation angle of multiparticle chains to control the phase difference of a stroke in each artificial cilium. This technique would help to realize metachronal waves of artificial cilia..
4. Fujio TSUMORI, Yuki TANAKA, XU YANG, Toshiko Osada, Hideshi Miura, Development of improved solid oxide fuel cell electrolyte sheet by microimprinting for layered material, Japanese Journal of Applied Physics, doi:10.7567/JJAP.53.06JK02, 53, 06JK02-1-06JK02-6, 2014.05, At present, the solid oxide fuel cell (SOFC) is attracting much attention because it possesses the highest power generation efficiency among many types of fuel cell, and SOFC emits only water that does not harm the environment. Recently, the electrolyte structure for SOFC has been processed into various forms to increase the efficiency of SOFC. In this work, we tried to improve the performance of SOFC by changing the mesostructure on the interfaces between the electrolyte and electrodes. This hundred-micrometer-scaled mesostructure has been proposed to increase the reaction on the interfaces. However, there has been no effective method of fabricating the cells with the microstructure along the interfaces. We have already proposed the micro powder imprint (µPI) method to create fine patterns on ceramic samples. In this study, the µPI method for layered material was newly developed to fabricate the micropatterns on both sides of an electrolyte sheet. The optimization of process parameters, such as compounding ratio, debinding temperature, and sintering temperature, was examined to obtain desired wavy patterns on both surfaces of the electrolyte sheet..

, Micro TAS 2017, 2017.10, We propose a new three-dimensional (3D) printing system for magnetic elastomer, which is composed of photo curable resin dispersed with magnetic particles. The obtained structure is magnetic and flexible so that they can work as an actuator by changing the applied magnetic field. During the curing process, a magnetic field is applied to set magnetic anisotropy at the curing portion, and we can design the motion of the actuator using this anisotropy. It means that we can not only print the 3D-structure but also print the deformation of printed actuator..

We employed an imprint process to give fine patterns onto a ceramic electrolyte sheet. The imprint process is a powerful tool to transcribe nano- to micro-patterns on materials. In the present work, a sheet of ceramic compound material was prepared, and micro patterns were given on the sheet. After debinding and sintering, dense ceramic sheet with fine patterns were obtained. We prepared three kinds of electrolyte sheets with different surface patterns using this technique. After applying anode and cathode layers, the three fuel cell samples were assembled to test the cell performance. It was resulted that the finer pattern caused the best performance in the three samples..

TSUMORI Fujio, HATAMA Kenji, KANG HYUNGOO, Osada Toshiko, Miura Hideshi, Magneto-FEM analysis for Micro Actuator using Array of Magnetic Elements, IEEE-NEMS2013, 2013.04, This paper reports a magnetic actuator using interaction between micro magnetic elements. It was already reported that the present actuator can work even if the structure was miniaturized to nano-scale. In the present work, simple fabrication process with photolithography and PDMS casting was employed to obtain beam type structures with micro array of magnetic elements on their surface. Two samples with simple grid patterns were prepared for testing. These samples had the same grid pattern but different orientation, which caused directly opposite bending deformation under the same applied magnetic field. We used magneto finite element method (FEM) to explain the behavior of the present actuators..
