Abstract:
A yaw-rate sensor, comprising:a substrate; a first coriolis element; a second coriolis element; an excitation arrangement to induce the first coriolis element and the second coriolis element to oscillate parallel to a first axis; a detection arrangement to verify a deflection of the first coriolis element and the second coriolis element based on a coriolis force in a second axis that is perpendicular to the first axis, the first axis and the second axis being parallel to the surface of the substrate; and a coupling spring to connect the first coriolis element and the second coriolis element to each other, and that is yielding in the first axis and in the second axis; wherein the first coriolis element and the second coriolis are arranged side-by-side and above a surface of the substrate.
