Abstract
A miniature actuator, in which a shape-memory alloy is driven photothermally by a laser diode, is described. The force of 9.8 mN and the displacement of 58 μm were obtained by irradiation with a laser power of 10 mW for the shape-memory alloy. The cutoff frequency for the vibration amplitude of this actuator was 0.2 Hz.
