Abstract
In this paper, a dynamic model of simply supported ionic polymer- metal composite (IPMC) beam resting on human tissues is developed. The IPMC beam is actuated by an alternative electric potential. The bending moment due to electric potential is obtained by Nemat- Nasser's hybrid actuation model. Analytical solution of transverse vibration is obtained to describe the vibration response of IPMC beam to a command of electric potential. Pressure generated by IPMC beam on human tissue is estimated by numerical integration. Comparison shows that the generated pressure is comparable with experimental data from literature. The developed model is useful not only for the biomedical devices that employ IPMC materials but also for any other applications that utilize the vibration of IPMC materials.
