Outline of Final Research Achievements

Unlike currently a macro-motor system, a micro-motor system needs to work in a smaller space where viscous effect is much larger.
In this study, we proposed a simple micro-motor system wherein a micro-particle exhibits a cyclic motion continuously in silicon oil under DC electric field. We found that a micro-particle exhibits various types of cyclic motions depending on its shape, and that the speed is controlled by strength of electric field. We also investigated relationship between its cyclic motion and electric current to elucidate the motion mechanism.

Academic Significance and Societal Importance of the Research Achievements

本研究課題によって得られた知見を基にすることで、マイクロモーターやポンプといったマイクロデバイスの動力源としての実用化の可能性が広がると考えられる。本システムの現在の問題点は、安定な運動を取り出すためには100 V程度の高い印加電圧が必要なところにある。しかしながら、今後システムをダウンサイジングすることで電場を強化し、乾電池程度(数ボルト)の微弱な直流電圧で安定な運動を取り出すことができれば、低消費電力で扱いやすい次世代の革新的マイクロデバイスの開発に貢献できると考えられる。
