Résumé
Ionic polymer-metal composites (IPMCs) are widely studied for their potential in soft actuation applications due to their ability to exhibit large bending displacements under low applied voltages. While prior research has extensively explored the impact of geometry on actuation force and displacement, the influence of membrane thickness on actuation dynamics, particularly reaction time and back relaxation behavior, remains underexplored. This study investigates the effect of membrane thickness on IPMC actuation performance using a multiphysics simulation approach. A finite element model based on an established electromechanical framework is implemented to capture the transient response of IPMC actuators with varying thicknesses. Simulation results show that increasing membrane thickness reduces both maximum and steady-state displacement due to increased bending stiffness. Furthermore, thicker membranes exhibit longer reaction times and more pronounced back relaxation, suggesting that relaxation dynamics are primarily diffusion-limited.
