Bending deformation of a Flemion-based IPMC (a gold plated Flemion) upon applied low electric field across its thickness is dominated by non-uniform equilibrium hydration. Non-uniform equilibrium hydration that leads to a permanent deformation is expressed by the “equilibrium hydration state” of the membrane under ion concentration gradients. Consequently, there is strain distribution due to different hydration throughout the thickness. In the present study, finite element formulation is conducted for the basic field equations governing electrochemical-mechanical response of a gold plated Flemion actuator upon applied electric field. Some numerical studies are carried out in order to show the validity of the present formulation.
