Abstract

An actuator device includes at least one actuator element, which consists at least partially of a magnetically shape-shiftable material and which is configured at least for the purpose of causing a movement of at least one actuation element in at least one direction of movement by means of a contraction, and having a magnetic contraction unit, which is configured for the purpose of supplying a magnetic field acting upon the actuator element in order to generate a contraction of the actuator element. In the region of the actuator element, field lines of the magnetic field are aligned at least substantially parallel to the direction of movement.
