Disclosed is a micromechanical manipulator composed of substrate 1, heating elements and a manipulator arm 2 which is based on the principle of the bimaterial effect. Prior art bimaterial manipulators execute movements perpendicular to the surface of the substrate. However, it is often desirable to have a manipulator which executes movements in the surface of the substrate. The invented manipulator is based on the substrate surface counteracting steering of the manipulator arm with mechanical resistance, which leads to bulging and shortening of the effective length of the arm and thereby to movement in the surface of the substrate. The invented manipulator arm is suited as a drive means for elements, such as toothed disks or joints, which are movably disposed in the surface of the substrate.
