Abstract
A method for the mutual displacement of at least two parts of an actuator interconnected by a bridge, and such an actuator. The bridge which connects the two parts and extends parallel to a main surface is locally heated through and through with a temperature gradient which is minimized transverse to the main surface, and is subsequently cooled down whereby the length of the bridge between the parts is reduced owing to the plastic deformation which occurs, so that the parts are displaced relative to one another in a direction parallel to the main surface.
