ACTUATOR HAVING AT LEAST ONE CONTROL ELEMENT WHICH HAS THERMAL TRANSDUCER MATERIAL

摘要

Described is an actuator having at least one control element which has thermally activatable transducer material and which, as a result of the supply or dissipation of thermal energy, changes from a first shape state into a second shape state, and having a mechanical energy store which is operatively connected to the control element and which, when the control element is in the second shape state, exerts on said control element a restoring force which returns the control element into the first shape state. The invention is characterized in that the mechanical energy store has an elastomer body which, at least in regions, is in direct physical and thermal contact with the control element, and in that the elastomer body is connected in a spatially fixed manner to the control element at at least two spatially separate joining regions along said control element, such that in the event of a change in shape of the control element, the elastomer body is subjected to a compression or elongation which generates the restoring force.
