Abstract

In this paper, we study the charge dynamics of ionic polymer metal composites (IPMCs) in response to an imposed time-varying flexural deformation. IPMC chemoelectromechanical behavior is described through the Poisson-Nernst-Planck framework, and the method of matched asymptotic expansions is utilized to establish a closed-form solution for the electric potential and counterion concentration in the IPMC. This solution is, in turn, leveraged to derive a mathematically tractable distributed circuit model of IPMC sensing.
