Abstract:
A yaw-rate sensor comprising: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 substrate; and 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 a surface of the substrate; wherein the first Coriolis element and the second Coriolis element are arranged side-by-side above a surface of a substrate, and the first Coriolis element and the second Coriolis element oscillate in phase opposition to each other on a first path and a second path that, without an effect of the Coriolis force, are a first straight line and a second straight line that are parallel.
