Fabrication of Stacked Rotary Actuator Using Bio-molecular Motor

Abstract

In this paper, we propose a stacked rotary actuator, which is a high power actuator driven by molecular motors. By stacking rotation units driven by molecular motors, the number of molecular motors working cooperatively increases and we expect to realize a high power actuator. In order to fabricate rotation units, it is necessary to control the orientation of the molecular motor. In this study, orientation control was performed using SU-8 microstructure. For stacking rotation units, we designed the microstructure which can fabricate many rotation units at once. The results confirm that the molecular motor were circularly oriented along the wall surface of the microstructure.
