Abstract

An actuator device includes at least one stationary unit, with at least one electromagnetic actuator element which is movable relative to the stationary unit, and with at least one shape-memory element which is implemented at least partly of a shape-shiftable shape-memory material, wherein the shape-memory element is configured, in at least one operation state, to at least partly hinder a movement of the actuator element in a first movement direction and in a second movement direction that differs from the first movement direction, at least via a mechanical deformation.
