YAW-RATE SENSOR AND METHOD FOR OPERATING A YAW-RATE SENSOR
First Claim
1. A yaw-rate sensor, comprising:
- a substrate having a main plane of extension for detecting a yaw rate about a fist axis extending parallel to the main plane of extension; and
a first Coriolis element, a second Coriolis element, a third Coriolis element, and a fourth Coriolis element;
wherein;
the first Coriolis element and the fourth Coriolis element are configured to be driven in the same direction parallel to a second axis, extending parallel to the main plane of extension and perpendicularly to the first axis;
the first Coriolis element and the second Coriolis element are configured to be driven in opposite directions parallel to the second axis; and
the first Coriolis element and the third Coriolis element are configured to be driven in opposite directions parallel to the second axis.

Abstract
A yaw-rate sensor includes: a substrate having a main extension plane for detecting a yaw rate about a first axis extending parallel to the main extension plane; a first Coriolis element; a second Coriolis element; a third Coriolis element; and a fourth Coriolis element. The first Coriolis element and the fourth Coriolis element are drivable in the same direction parallel to a second axis extending parallel to the main extension plane and perpendicularly to the first axis. The first Coriolis element and the second Coriolis element are drivable in opposite directions parallel to the second axis. The first Coriolis element and the third Coriolis element are drivable in opposite directions parallel to the second axis.
