| Outline of Research at the Start |
無配線・遠隔制御可能なマイクロアクチュエータの開発は，微小機械の小型化・高性能化に不可欠である．本研究では，磁性ナノ粒子の交流磁場中における発熱を駆動源とする，新規交流磁場応答アクチュエータ開発の基礎研究を行う．まず，粒子サイズと凝集状態の異なる磁性ナノ粒子を調製し，発熱量と交流磁場周波数の関係を明らかにする．そして，磁性ナノ粒子と熱応答性ゲルを組み合わせたアクチュエータを複数個作製し，交流磁場周波数により，複数のアクチュエータを1つのコイルで個別制御可能なシステムの開発を目指す．

| Outline of Final Research Achievements |
We devised microvalves that can be remotely controlled without electrical wiring but utilizing an alternating magnetic field, and we conducted basic research for its development. A manufacturing process of the microvalves was established and the microvalves were prototyped. Opening/closing drive of the valves by the AC magnetic field was confirmed. The microvalves were actually driven by applying the AC magnetic field. Although further studies are needed in the future, this study confirmed the feasibility of the proposed microvalves that can be remotely controlled without wiring.
