Abstract: Based on the multiphasic mixture theories, a multiphysical mathematical model, called the multi-effect-coupling electric-stimulus (MECe) model, has been developed in this dissertation to simulate the responsive behaviors of electric-sensitive hydrogels when they are immersed into a bath solution subjected to an externally applied electric field. In order to solve the complicated MECe model, a novel meshless technique, termed Hermite-Cloud method, is employed in the present numerical simulations. After the experimental validation of the developed MECe model, one-dimensional steady-state and transient simulations are carried out for analyses of equilibrium and kinetics of the electric-stimulus responsive hydrogels, respectively. The influences of key physical parameters on the responsive behaviors of electric-sensitive hydrogels are also discussed in details. The simulated results show a good agreement with the experimental data and the conclusions drawn according to the discussions provide useful information for researchers and designers in the bio-micro-electro-mechanical systems (BioMEMS) field.
