In this paper, the equilibrium behavior of the smart hydrogels responding to the electric voltage and pH coupled stimuli is simulated by a chemo-electro-mechanical multi-field model, termed the multi-effect-coupling pH-electric-stimuli (MECpHe) model. It consists of coupled nonlinear partial differe...
