概要

論文の詳細を見る
A coil made of a thin shape memory alloy wire, superior to electrostatic and / or piezoelectric devices in power-weight ratio and acceptable drive range, was used for the actuator of micromanipulator. As the first step of this study, the authors made a micromanipulator having diamond end-effector using the shape memory alloy actuator that can handle micro elements, as small as several to several ten micrometers, made of diamond. The shape of end-effector was first designed and the distribution of stress caused during its operation was simulated by the FEM analysis to avoid possible harmful stress concentration. The manipulator produced worked satisfactorily to grip and locate diamond micro elements of the size described.
