Abstract

In this paper, we analyze the charge dynamics of ionic polymer metal composites (IPMCs) in response to voltage inputs composed of a DC bias and a small AC voltage. IPMC chemoelectrical behavior is described through the Poisson-Nernst-Planck framework. The physics of charge build up and mass transfer at the electrodes are modeled through metal particle layers. Perturbation methods are used to establish an equivalent circuit model for the IPMC electrical response. The proposed approach is validated through comparison with finite element results.
