Actuator element and method for operating an actuator element

摘要

The invention relates to an actuator element (10) comprising an actuator (12) which comprises a shape memory alloy and is designed to shorten or lengthen in its longitudinal extension direction in an excited state, an electronic control unit which has a carrier element (18) and a A plurality of electronic components (26) for exciting the actuator (12) on the basis of a control signal, and a movable component (20) which is coupled to the actuator and movable by means of the actuator (12) relative to the carrier element (18), wherein the The carrier element (18) defines a guide section (16), in particular a dimensionally stable guide section, by means of which the actuator (12) is guided along its direction of longitudinal extent.
