Shape memory alloy actuator 0301122-189
An actuator that uses shape memory alloy.
Shape memory alloy actuators are compact, light, and produce large
forces. The actuators can be driven repeatedly in a heat cycle or can be controlled arbitrarily by
switching the electric current through the actuator itself. Lately, attempts have been made to use
the alloys to build a servo system that has an appropriate feedback mechanism and a cooling system,
intended for applications where quick response is not necessary in particular. Application examples
under development are microgrippers for cell manipulation, microvalves for regulating very small
amounts of flow and active endoscopes for medical use.
