Paper Abstract

An optical actuator has some interesting characteristics, such as no generation of magnetic noise and receiving the energy remotely. A novel two-dimensional actuator using temperature-sensitive ferrite is proposed. It consists of a moving object made by magnet and a base with temperature-sensitive ferrites that are aligned as a matrix. When the temperature-sensitive ferrites are irradiated by the light beam, their magnetic susceptibility is decreased. The moving part moves along opposite side of irradiation light because of balance of magnetic force. The moving effect irradiated by light beam is simulated and measureed. The two dimensional moving of a magnet with 2.4 mm of squire is demonstrated by using 10 x 8 sets of ferrite with 1.5 mm of diameter.
