Abstract
A micromechanical rotation rate sensor, in particular for use in motor vehicles, includes a substrate, at least one seismic mass, which is arranged in a sprung manner on the substrate, drive means for production of a periodic movement of the seismic mass, force detection means for detection of a Coriolis force, which acts on the seismic mass as a result of rotation about a rotation axis which is at right angles to the excitation direction, and measurement means, wherein the measurement means are designed for measurement of structural deviations of the rotation rate sensor.
