Photothermal actuator composed of optical fibers

摘要

An optical actuator features characteristics such as energy supplied remotely in wireless and no generation of magnetic noise. We proposed a new type of an actuator that is driven by the light. It is composed of three optical fibers as a leg jointed to a base. The fiber cut at an angle at the end is occurred a photothermal effect respond to flashed incident beam with a constant cycle from other side of the fiber. This effect makes the end of fiber a stretching vibration. A size of the optical actuator is 3 X10 mm and it moved 25 micro-mm per second at 12mW (4Hz) of input power. We discuss these experimental procedures and the results of movement.
