Abstract
An actuator having two parts ( ) which extend in a main plane and are mutually connected by three bridges ( ). The bridges can be shortened in respective shortening (Y , Y , Y ) directions parallel to the main plane by local heating and subsequent cooling down of the bridges. According to the invention, the shortening directions of the three bridges are parallel, and the two parts of the actuator are rotated relative to one another about an axis of rotation ( ) extending perpendicularly to the main plane through alternate shortening of two adjacent bridges ( or ) of the three bridges. The two parts of the actuator can be rotated relative to one another in two opposite directions.
