The purpose of this research is to develop a method to perform a finite-element analysis (FEA) coupling diffusion of water and structure (deformation) on electro-active polymer (EAP) such as Nafion 117 electrified in the water. In the resent report, some experiments were carried out to find properties of Nafion 117 that will be used in the FEA. First, the experiments in which wet Nafion 117 was electrified in the distilled water were performed to examine relations between voltage, current and deformation. Then the volume content of water on Nafion 117, coefficient of linear expansion and specific volume were determined measuring the volume and mass of test pieces of dried and wet Nafion 117. Then the experiment on free vibration of a cantilever of wet Nafion 117 in the distrilled water and the FEA following the experiment were carried out in order to find Young's modulus of the wet Nafion 117. The coefficients, α and β of Rayleigh were also found by comparing the experimental results and the calculated ones.
