Polypyrrole–metal Coil Composites as Fibrous Artificial Muscles

Abstract

Abstract A polypyrrole deposited electrochemically on tungsten coil showed 11.6% strain and 0.20 N force induced electrochemically. The W coil significantly reduced iR drop of the PPy, resulting in improving performance of the actuator. The fibrelike structure was suitable for applications of artificial muscles.
