초록

A shape memory alloy actuator comprising a body (1) connected through an arm (5) with an activating member (15), the body (1) being arranged for rotation around a pivot (2) and connected to a first wire (9) and a second wire (10) of a shape memory alloy such as nitinol and to a biasing means such as a tension spring (6) such that heating and therefore shortening of the wire (10) rotates the body (1) counter-clockwise such that the tension spring (6) is in its cocked position while heating (shortening) of the wire (9) and cooling (lengthening) of the wire...
