Shape-Memory Effect (SME) alloys have been known and available for many years. Principal applications have used the nickel-titanium SME alloys in high-performance products such as aircraft hydraulic couplings. A practical one-pound, three-quarter-inch-stroke, linear actuator using shape-memory effect (SME) metal is described. The actuator is a helical spring made with nickel-titanium shape-memory metal alloy. It compresses or 'shrinks' when heated with an electric current. Design of the actuator which includes protection against ancillary jams is described. Performance data showing actuation time versus applied current, ambient temperature and applied load is presented.
