| Outline of Final Research Achievements |
Functionally patterned surfaces using microscale surface patterns have been widely applied in industrial fields. Examples of industrially common applications include superhydrophobic, or superhydrophilic surfaces, and antireflection structures. These functional surfaces are achieved through "static" microstructures, meaning fixed patterns. In this study, we propose a method to dynamically alter the microscale patterns by manipulating the structure and shape of the micro-patterns themselves. We demonstrate the feasibility of creating surface-driven structures at the millimeter scale and provide a fabrication method for microscale structures as well.

微生物の表面に見られる繊毛構造のような「うごく」表面構造を実現できれば，さまざまな機能を実現できる．しかしながら，駆動表面構造を実現する手法は確立されていなかった．本研究では磁場駆動型ピラー構造をアレイ状に配置することでこのような機能表面を実現した．試作構造はミリメートルスケールのピラーであるが，微生物生体に近いマイクロスケールのピラーアレイ構造を実現するための手法も提示した．これらの技術は，微細流路内でのマイクロポンプや防汚表面といった工学的な応用につながるものと考える．
