Summary: | The two-dimensional finite element formulation for the basic field equations governing electrochemical responses of ionic conducting polymer-metal composite (IPMC) actuators is proposed in the present study. Biaxial bending deformation of a platinum plated Nafion actuator having 4 electrodes is dominated by internal water redistribution, which is associated with electroosmosis of hydrated ions and self-diffusion of free water molecules. Two processes can be considered separately in the way that fast electroosmosis is followed by much slower self-diffusion. Some numerical studies for IPMC actuators with several types of electric field are carried out in order to show the validity of the proposed formulation. |
