Abstract: An actuator device for bidirectional adjustment of an adjusting body constructed for interaction with an adjustment partner and preferably realized as a tappet (14), having first adjustment means (10), which have expansion means having a magnetically effective shape-memory alloy material (12) and exerting an adjustment force, particularly a pushing force, on the adjusting body for moving the same along a first adjustment direction, which carry out an expansion generating the adjustment force as a reaction to a first energizing of first coil means (16), and second adjustment means (20; 20′, 34) assigned to the adjusting body and provided separately from the expansion means and the first coil unit, which are constructed for moving the adjusting body in a second adjustment direction opposite to the first adjustment direction, characterized in that the second adjustment means have an electromagnetically or electromotively driven actuator and therefore for moving the adjusting body in the second adjustment direction construct a drive, which can be activated as a reaction to signal loading, particularly a second electrical energizing.

Abstract: A gripper device (16; 30; 56; 90; 120) which is designed so as to be movable along a movement path, and which serves for grasping and holding a workpiece (70) and for moving the workpiece along the movement path, with at least one first contact section (18; 38; 66) which, to produce an operative pairing with the workpiece that effects the gripping or holding action, can be driven relative to a second contact section (20; 40; 68), which first contact section is assigned actuator means (22; 44; 54; 128), which are designed to exert a drive force in reaction to the application of a magnetic field, and which are composed of a magnetic shape-memory alloy material, wherein the actuator means for magnetic interaction are formed, for the application of a magnetic field, with magnetic field generating means that are static at one position of the movement path (52; 80; 86; 88), and/or with magnetic field generating means that are provided so as to be movable independently of the gripper device.

Abstract: A positive-displacement pump device has at least one shape-memory unit including at least one magnetic shape-memory element, which is configured to convey at least one medium along at least one transport direction, wherein the positive-displacement pump device includes at least one deformation unit, which is configured, for the purpose of providing a transport volume, to deform the magnetic shape-memory element, at least in an idle state in which the positive-displacement pump device is free of a current and/or voltage supply, by a pressure force and/or traction force acting in the transport direction such that the magnetic shape-memory element includes at least one first partial region and at least one second partial region which differ from one another at least by their magnetic orientations.

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.

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.
