Abstract
The purpose of this study is to investigate the properties of the shape memory alloy by using a fluorine-based inert liquid. We have made an SMA actuator having a cooling mechanism. We are also considering the application to the driving source of pediatric prosthetic hand power to the actuator. In this paper, we describe the development methods and prototype of the SMA actuator. Furthermore we explain experimental results of the basic characteristic. As the results, we confirmed that the fluorine-based inert liquid has a usefulness for the cooling of the SMA.
