Patent ID: 8794066

Claim:
A micromechanical Coriolis rate of rotation sensor for detecting rates of rotation (Ω X , Ω Y , Ω Z ) with components about measurement axes in three mutually orthogonal spatial directions (X, Y and Z axis), comprising: a substrate ( 1 ); a detection mass ( 3 ); at least two drive masses ( 4 a , 4 b , 4 c , 4 d ), the drive masses ( 4 a , 4 b , 4 c , 4 d ) each driveable relative to the substrate to provide a primary movement (V Xa , V Yb , V Xc , V Yd ), wherein the direction of the primary movement (V Xa , V Yb , V Xc , V Yd ) of one of the at least two drive masses ( 4 a , 4 c ) is perpendicular to the direction of the primary movement (V Xa , V Yb , V Xc , V Yd ) of another of the at least two drive masses ( 4 b , 4 d ); wherein the detection mass ( 3 ) is coupled to the drive masses ( 4 a , 4 b , 4 c , 4 d ) in such a manner that the detection mass ( 3 ), due to a secondary movement of the drive masses ( 4 a , 4 b , 4 c , 4 d ) due to Coriolis force under action of an external rate of rotation to be detected can be excited to perform a detection movement; and wherein the detection mass ( 3 ) can carry out rotational oscillations about axes of rotation in the three mutually orthogonal spatial directions (X, Y, Z) relative to the substrate as a detection movement.
