Ion Behavior and Drive Principle of Ion-Conductive Polymer Nafion-Based Film Actuator

Abstract

We have developed a polymer actuator that has rapid displacement response under the applied voltage. The differences in size and velocity between cations and anions play a major role in the bending mechanism of the actuator. We have predicted the dynamic behavior of an ion-conductive polymer film actuator that uses carbon electrodes. We have also clarified the bending mechanism of an ion-conductive polymer actuator that uses carbon electrodes and includes a bending back motion.
