This talk discusses analytical simplification of a multi-physics model for ionic polymer-metal composite (IPMC) sensors. Some methods including finite element method, and assumed mode method based on separation of variables are introduced. For the finite-element or the assumed-mode simulation, we have built in-house MATLAB programs. The obtained approximated models are represented by ordinary differential equations, and the computational cost is greatly reduced by the proposed simplifications. The magnitudes of the error in the approximated models for open-circuit voltage are kept acceptable level within at most 2%, although the computational time is greatly reduced to 1/100 to 1/1000.
