Abstract
Ionic polymer-metal composite (IPMC) is promising material in biomedical applications, since IPMC is soft and flexible, leading to the safety of the device itself. The purpose of this study is to investigate the biocompatibility of IPMC by in vitro experiment, in order to evaluate the applicability to biomedical field. Embryo cell of cynops pyrrhogaster could be cultured around IPMC films. Colony-forming test using Chinese hamster lung fibroblast cell shows high cytotoxicity of IPMC. Further tests are necessary to investigate the cause of cytotoxicity of IPMC. IPMC actuators immersed in medium for 7 to 13 weeks could show bending response driven by a rectangular wave and a sin wave.
