Abstract

A rotation rate sensor for detecting a rotational movement of the rotation rate sensor about a rotational axis extending within a drive plane of the rotation rate sensor include: a first rotational element, a second rotational element and a drive structure moveable in parallel to the drive plane, the first rotational element being drivable about a first center of rotation to achieve a first rotational vibration in parallel to the drive plane, the second rotational element being drivable about a second center of rotation to achieve a second rotational vibration in parallel to the drive plane, the drive structure being (i) coupled to the first and second rotational elements, and (ii) configured to generate a drive mode in phase opposition of the first and second rotational vibrations.
