技術說明

本發明揭露一種具圖案化磁性薄膜之微米磁性致動器與磁性夾取器之製備方法。微米磁性致動器之設計包含高可撓性微伸縮結構與圖案化磁性薄膜。圖案化磁性薄膜之非等向性細長型狀，造成單一區域磁性。磁性夾取器之設計包含雙夾具包含微伸縮結構、微夾具結構與圖案化磁性薄膜。藉由磁力驅使作動過程，使雙夾具產生側向位移而夾具間彼此互相靠近與遠離，造成如手臂之開合行為。控制磁性夾取器開合量則有抓取功能，另因磁膜具備之磁力吸引性，可以吸引流體中磁性標的物移動至磁性夾取器。 The present invention discloses the fabrication of nano-/micro- actuator and gripper with patterned magnetic thin film. The design of the actuator comprised highly flexible stretchable structures and patterned magnetic films. The magnetic thin film with elongated shape caused magnetic anisotropy, resulting in single domain resembled magnetic configuration. The design of the magnetic gripper contains double fixtures, double stretchable structures and patterned magnetic thin films and driven similar process as the actuator. The lateral displacement of the double fixtures causes the fixture move near and away from each other and causes opening and closing behavior. By controling the opening and closing behavior of magnetic gripper, the function of grabbing object can be achieved, and due to the native magnetic attraction force of the magnetic film, the moving magnetically labeled target in fluid can be actively catch by micro gripper.
