We built up the way of fabricating ionic polymer metal composite (IPMC) actuator with palladium electrodes and evaluated the bending response under various temperatures. IPMC consists of a thin Nation^[○!R] membrane sandwiched between two thin palladium plates. The bending response of EPMC actuator was evaluated under the various temperatures. The results showed that the higher the temperature of ionic solvent was, the larger bending response IPMC actuator showed. Moreover, a simple beam model was introduced and compared with the experimental results.
