Abstract
The human body consists of skeleton, dermis and flexible muscle of spindle form. In this study, we aim to realize the artificial muscle that is comparable with natural muscle from the viewpoint of flexibility, power and response. It results to the serious problem such as the short circuit and intertwines together that bunches SMA coil springs like the natural muscle cells. We constructed a SMA artificial muscle actuator protected by "Rolled film tube" made of heat-resistant film as a mechanical element flexible in the axial direction, and experimented on characteristics of output force driven by PFM method as used in the natural muscle. Consequently, we found the possibility this actuator can be driven by natural nerve impulse.
