Abstract
An optical driven actuator has a feature of a non-contact for applying light energy remotely. It consists of a neodymium magnet as a movement, a ferrite magnet, two blocks of graphite and temperature sensitive ferrite. The neodymium magnet is levitated by magnetic force between the neodymium and ferrite magnet. When laser is irradiated on temperature sensitive ferrite, a magnetic force decreases by photo-thermal effect. As a result, the movement can be controlled in three-dimensional area.
