Abstract

A rotation rate sensor includes: a mounting device; a first drive frame having a drive, which is designed to set the first drive frame into a first oscillatory motion along an axis of oscillation relative to the mounting device; a first stator electrode; a first actuator electrode coupled to the first drive frame in such a way that in a rotary motion of the rotation rate sensor due to a Coriolis force, the first actuator electrode being displaceable in a first deflection direction relative to the first stator electrode; and an evaluation device configured to determine a voltage applied between the first stator electrode and the first actuator electrode, and to specify information regarding the rotary motion of the rotation rate sensor while taking the determined voltage value into account.
