Abstract :

Three multi-physics models were developed or presented to predict the transient nonlinear behavior of actuators/sensors based on stimuli-responsive polymer hydrogels. A true meshfree, implicit numerical scheme was conducted to solve the coupled transient nonlinear partial differential governing equations. For the developed models involving chemo-electro-mechanics, the transient responds of electric-sensitive hydrogels including the membrane deformation, ionic concentrations and electric potentials interior and exterior the membranes are numerically simulated and compared. And the parameters having important influence on the transient hydrogel deformation are also investigated.
