Outline of Final Research Achievements

The target of the present study is to construct micro-scaled mechanical machine with the scale of micrometer to centimeter. The main results are summarized as follows: 1) Rotational motor driven by constant DC voltage. Construction of rotational motion of sub-millimetre scale working in an organic solvent. 2) Photo induced fluid pumping and rotary motion. 3) Self-propelled motion induced by chemical potential under isothermal condition. It was found that cm-sized organic droplets undergo synchronized motion, both up-down motion and translational motion.

Academic Significance and Societal Importance of the Research Achievements

20世紀初頭、Einsteinは、Brown運動の理論を構築したが、これは線形非平衡の枠組みであった。近年、Jarzynskiが、線形関係の破れが、仕事の効率の限界に直接関係することを示すなど、非平衡物理学は発展してきてはいる。しかしながら、マイクロなスケールで、高効率で運動する機械を創出するといった、基本的な課題については未だ初歩な段階に留まっている。本研究では、非線形特性を活用することにより、マイクロスケールの「ゆらぎ」から、マクロな秩序運動をとりだすといったことをターゲットにして、国際的にみても先導的な研究を進めることができている。
