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.

An overcurrent protection device for a circuit to be monitored, includes at least one trigger unit, which is configured for an interruption of the circuit in at least one trigger situation and which comprises at least one conductor section, which is configured for a conduction of a current to be monitored, at least one trigger element, which comprises at least one magnetically and thermally shape-shiftable material and is, in the trigger situation, configured for a thermally-induced and/or magnetically-induced deformation in dependence on a current that flows through the conductor section, and at least one actuation element, which is operatively connected with the trigger element and is configured for a transmission of at least one actuation movement and/or at least one actuation force to at least one interrupter switch.
