Abstract

A yaw-rate sensor and a method for operating a yaw-rate sensor having a first Coriolis element and a second Coriolis element are proposed, the yaw-rate sensor having a substrate having a main plane of extension, the yaw-rate sensor having a first drive element for driving the first Coriolis element in parallel to a second axis, the yaw-rate sensor having a second drive element for driving the second Coriolis element in parallel to the second axis, the yaw-rate sensor having detection means for detecting deflections of the first Coriolis element and of the second Coriolis element in parallel to a first axis due to a Coriolis force, the second axis being situated perpendicularly to the first axis, the first and second axis being situated in parallel to the main plane of extension, the first and second drive elements being mechanically coupled to each other via a drive coupling element.
