Abstract:
1. A rotation rate sensor comprising: a substrate having a main extension plane; at least one drive electrode coupled to the substrate; at least one counterelectrode; a Coriolis element movable relative to the substrate, the Coriolis element being excitable, by way of the at least one counterelectrode coupled to the Coriolis element and the at least one drive electrode coupled to the substrate, to perform an oscillation deflection parallel to the main extension plane, the Coriolis element being deflectable, by way of a Coriolis force acting on the Coriolis element, to perform a detectable Coriolis deflection perpendicular to the main extension plane; and at least one compensation electrode positioned above the substrate and beneath at least one of the at least one counterelectrode in an overlapping fashion for at least partial compensation, as a function of the oscillation deflection, for a levitation force acting on the Coriolis element.
