Abstract

Attention has been focused on ionic conducting polymer-metal composites (IPMCs) as intelligent materials for artificial muscles and robotics for recent years. The two-dimensional finite element formulation based on the Galerkin method is conducted for the basic field equations governing electrochemical response of IPMC beams with two pairs of electrodes upon applied electric field. The three-dimensional finite element analysis is conducted for the deformation of IPMC beams due to water redistribution in the beams associated with the electrochemical response. Some numerical studies are carried out in order to show the validity of the present formulation. A computational modeling is also established for the electrochemical-poroelastic behavior of conducting polymers such as polypyrrole. The three-dimensional continuum modeling given by Della Santa et al. for the passive, poroelastic behavior of conducting polymers is extended to the formulation for the active, electrochemical-poroelastic formulation according to Onsager-like laws, which is combined with the one-dimensional equation for ionic transportation. The validity of the finite element formulation for these governing equations has been demonstrated by numerical studies for the passive and active responses of polypyrrole membranes.
