Abstract
A yaw-rate sensor is proposed having a first and a second Coriolis element ( ) which are arranged side-by-side above a surface ( ) of a substrate. The Coriolis elements ( ) are induced to oscillate parallel to a first axis. Due to a Coriolis force, the Coriolis elements ( ) are deflected in a second axis which is perpendicular to the first axis. The first and second Coriolis elements ( ) are coupled by a spring ( ) which is designed to be yielding in the first and in the second axis. Thus, the frequencies of the oscillations in the two axes are developed differently for the in-phase and antiphase oscillation.
