A model of the IPMC actuator using finite element method

Ionic polymer-metal composite (IPMC) is an attractive actuator among many electro-active polymers. In order to improve the performance of IPMC actuator, an IPMC actuator with the patterned surface was proposed. It is named the patterned IPMC actuator. In order to make use of its maximum effect, it is needed to establish a valid mathematical model. Among many models of IPMC actuator, the grey box modeling proposed by Kanno et al. was suited to model the patterned IPMC actuator. In this paper, we applied the grey box model based on Kanno's model. Theoretical and experimental results demonstrate that the model is practical and effective enough in predicting the bending displacement partly.
