Omnidirectional flex-type shape memory alloy film actuator individual, process for producing the same, and optical fiber

摘要

The invention provides a shape memory alloy film actuator individual improved in mechanical reliability, miniaturized, and produced inexpensively, on a massive scale, and in a short time as compared with omnidirectional flex-type actuators in the related art depending upon the coils of a shape memory alloy. A shape memory alloy film is deposited on the outer periphery of a solid small-gage wire or a hollow capillary and integrated with the wire or the capillary, and then driving elements divided plurally are formed, thus to produce the shape memory alloy film actuator individual where omnidirectional flexing is possible.
