Fundamental research on polymer material as artificial muscle

Presently, breakthrough industrial technology and scientific technology produce various instruments of downscale and weight saving. But the metal parts are widely used for magnetic motors. It is difficult to lighten the weight and to miniaturize the motor. Therefore, we need small, light actuators that can be built into motor. We focus attention on the polymer material artificial muscle that responds to electrical stimulation with a significant shape or size change. In this research, the artificial muscle was produced by using the conductive grease and the polymer material. We used several kinds of polymer material films in our experiments to compare the performance of them. The displacement when the voltage is applied to electrode was measured. At last the result and conclusion are given.
