الملخص
(EN)
A self contained shape memory alloy (SMA) mechanism (50) is presented comprising a first anchor (52) and a second anchor (54) with a SMA actuator (56) and a return member (58) disposed therebetween. The SMA actuator (56) is a SMA bundle formed of single wires. The return member (58) is a linear spring surrounding the SMA actuator (56). Each mechanism (50) also includes a heating means. In operation, with the SMA actuator (56) in a martensitic state, the spring (58) of the mechanism (50) stretches the SMA actuator (56). When the SMA actuator (56) is heated to achieve its austenitic state, the force of the SMA actuator overcomes the force of the spring and pulls the anchors (52,54) thereby actuating at least one of the anchors (52,54). One major benefit of the mechanisms (50) is the ability to repeatably generate high active force in a compact package.
