Abstract:
A rotation rate sensor including a substrate having a main plane of extension, a first rotation rate sensor structure for detecting a first rotation rate about an axis that is in parallel to a first axis extending in parallel to the main plane of extension, and a second rotation rate sensor structure for detecting a second rotation rate about an axis that is parallel to a second axis extending perpendicularly with respect to the main plane of extension. Also included is drive device for deflecting a first structure of the first rotation rate sensor structure, and a second structure of the first rotation rate sensor structure, and also for deflecting a third structure of the second rotation rate sensor structure, and a fourth structure of the second rotation rate sensor structure, in such a way that the first, second, third, and fourth structures are excitable into a mechanically coupled oscillation.
