A shape-memory-effect actuator is provided having a shape-memory-alloy spring and a compensator spring. The alloy spring is operatively connected to a concentrically-mounted compensator spring by the use of a protective support housing which surrounds the alloy spring. The actuator includes a shape-memory-alloy spring and a compensator spring that regulates the operating conditions of the shape-memory-alloy spring to a chosen corresponding memory relaxation curve. The memory relaxation curve defines the actuator\s operating stress, stroke and life.
