Various kinds of actuators are now required to widely extend their applications. The SMA (shape memory alloy) actuator is one of these and has special functions. However, it is difficult to improve response velocity with this actuator because it depends on heating or cooling method. In this paper; we propose to use a thermomodule with thermoelectric effects (peltier effects) of a semiconductor to solve such problems, and fabricate a SMA actuator composed of four SMA sheets (170×5×0.4 mm) with thermomodules. As a result, the time constant of cooling response could be improved considerably (3.5sec) in step motion in several times, and its validity was confirmed by these experimental results.
