Artificial muscle actuators based on ionic electroactive polymers(IEAPs)are attracting flourishing research interests because of their unique features such as flexibility,lightweight,low impendenc and low-energy consumption.Traditional ionic-polymer metal composite(IPMC)actuator has the defects of durability in open air due to evaporation of water contained in the electrolytes,resulting in corresponding loss of performance.This article mainly focuses on the development of a novel IEAP based artificial muscle actuator.
