Ionic polymer-metal composite (IPMC) materials are promising candidates for soft robotics and artificial muscle applications. The primary actuation mechanism in such devices is ion migration in a polymer membrane, localized swelling, and a corresponding overall material deformation, which is multiphysics in nature. Simulations were performed for a rectangular IPMC actuator in response to a sinusoidal input voltage. Cation migration simulations provide insight into the underlying physics of such devices.
