| Outline of Final Research Achievements |
This research aims to develop a series of technologies for generation and measurement of micro-order displacement, velocity and force, and fabrication and driving of spatial several-hundred micro scale mechanisms of complicated structure capable of being deformed by external forces, based on the knowledge of noncontact magnetic actuation and analysis and design of elastic multiple-loop mechanisms. The obtained results can be summarized that analysis, design and fabrication techniques of micro elastic mechanisms composed of multiple chains of micro resin droplets containing a lot of magnetic particles, and modeling, analysis, measurement and control technology of magnetic driving and its implementation for an actual experimental setup have been developed. Based on this, a fabrication of a micro gripper, and grip / release operation of micro glass beads have been experimentally achieved.

本研究は，浮遊しているプローブを扱う限り単一のそれの位置・速度・発生力しか制御できないという従来のマイクロ磁気駆動技術の制約を解消し多自由度運動を創成可能なマイクロ機械システムを実現するために，全体が柔軟かつ磁性材料で構成されるマイクロ空間機構の設計・製作および磁場を用いた非接触駆動を実現する一連のモデル化・解析・設計および実装に資する技術を開発した．得られた成果は関連分野の進歩に寄与するものであり，開発技術を用いて直径100μmのガラスビーズを把持・開放可能なマイクログリッパ機構が試作され，バイオエンジニアリング分野およびそれ以外の産業分野への応用が期待される．
