Outline of Final Research Achievements

In order to realize a highly versatile high-performance wireless micromanipulator with a wireless actuator using a temperature-sensitive magnetic material (TSMM), it is necessary to integrate the grasping, rotation, and planar motion functions into one unit (Issue 1) and to realize a cooling device for wireless actuators that are used for a long time (Issue 2). For (Issue 1), the prospects of the two methods were investigated by magnetic analysis and experiments using a prototype device. For (Issue 2), the effective cooling system for wireless actuator technology using TSMM was designed, and fabricated and its usefulness was verified.

Academic Significance and Societal Importance of the Research Achievements

感温磁性体とレーザ光を用いたワイヤレスアクチュエータは，材料の熱磁気特性を利用するため，本質的に単純な構造と微小化に適しワイヤレスで駆動できるというほかに類を見ない利点を持つ一方で，制御性が低く実用化のためには解決しなければならない未解明，未解決な課題がある．本研究課題では，そのための重要な課題に取り組み，まだ十分ではないが，その成果として有望な解決方法を提示しており，学術的意義が高く，社会的に有用な知見を提供している．
