Abstract:
A material for an actuator is provided which is reduced in weight, can be micro-miniaturized and can be used stably in a gas phase such as in atmospheric air safely, and an actuator using the material is provided. The material used for the actuator comprises a material formed by mixing fine conductive particles with a polymer material having a large absolute value of thermal expansion coefficient.
