振動誘起流れを用いた微小物体の角度制御

抄録

Attitude control is essential technique for cell surgery or three-dimensional observation of microobjects in field of cell biology and medicine. Previously, we proposed the three-dimensional rotation of microparticles using vibration-induced flow. Vibration-induced flow is generated by the high-speed vibration of a microobject. Therefore, we can change angular velocities of a microobject by applying different amplitude of the vibration. In this paper, we construct an angle control system for microobjects toward attitude control using vibration-induced flow. We constructed the system of visual feedback control using the voltage as manipulation variable. We succeeded in controlling the angle of microobject with an angle error within 3 degrees at horizontal rotation and vertical rotation. We will realize attitude control by using proposed method in the future.
