In this chapter, the two models previously published are reviewed first for the responsive hydrogels, which providing the basis for the present multi-effect-coupling electric-stimulus (MECe) model. It is followed by development of the MECe model, in which four important governing equations are formulated to characterize the diffusive ion concentrations, the electric potential, the interstitial fluid pressure and the deformation of hydrogel, respectively. The non-dimensional form of the MECe governing equations is then presented and the boundary and initial conditions are proposed accordingly. After validation of the MECe model by comparison with the experimental data published in open literature, the steady-state simulation is conducted for equilibrium analysis of the electric stimulus-responsive hydrogel and the transient simulation for kinetics analysis of the smart hydrogel.
