Beschreibung
Zusammenfassung:	Multi-stable SMA actuator comprising two shape memory alloy wires (1, 2) in antagonistic configuration that allow to define multiple stable positions of a movable element (12), said positions being maintained by movable stoppers to lock the movable element, that do not require power and are disengaged by the shape memory alloy wires (1, 2) upon actuation thereof.
