Abstract

Ionic polymer-metal composites (IPMCs) generate electrical potential under deformation and can be used as sensors. Recently, Zhu et al. have proposed a sensor model which describes distribution of cations, water molecules and electrical potential under bending deformation. In this paper, we discuss a simplification of the multi-physical sensor model, which is represented by a set of nonlinear partial differential equations. The nonlinear partial differential equations are simplified and approximated into a set of linear ordinary differential equations, i.e., a state-space equation model. At the end, the simplified model is validated by comparing the simulation results with those of the partial differential equation model.
