Abstract:
1. A micromechanical element comprising: a movable functional element; a first retaining element, the first retaining element and the functional element being connected at a first junction; a second retaining element, the second retaining element and the functional element being connected at a second junction; a third retaining element, the third retaining element and the functional element being connected at a third junction; a fourth retaining element, the fourth retaining element and the functional element being connected at a fourth junction, the first retaining element and the second retaining element each comprising a piezoelectric driving element, the piezoelectric driving element of the first retaining element and the piezoelectric driving element of the second retaining element being configured to move the functional element in accordance with electric excitation, wherein the first retaining element is deformed upon a movement of the functional element, and wherein the piezoelectric driving element of the first retaining element is configured to detect a deformation of the retaining element so as to enable, on the basis of the detected deformation, determination of a position or of a state of motion of the functional element; and a control means, the control means being configured to control the electric excitation of the piezoelectric driving elements, and being configured to adapt the electric excitation of the piezoelectric driving elements on the basis of a detected position or state of motion of the functional element, wherein the control means is configured to determine, on the basis of a plurality of determined positions or states of motion, a dynamic deformation of the functional element, and is configured to adapt the electric excitation of the piezoelectric driving elements so as to reduce the dynamic deformation of the functional element.
