Patent ID: 7313958

Claim:
A rotational rate sensor, comprising: a substrate; a plurality of sensor elements including a Coriolis element situated over a surface of the substrate, wherein: the Coriolis element is capable of being induced to vibrate in parallel to a first axis, an excursion of the Coriolis element is detectable and is based on a Coriolis force in a second axis that is essentially perpendicular to the first axis, the first axis and the second axis are parallel to a surface of the substrate, and the plurality of sensor elements are at least partially movable with respect to the substrate and the plurality of sensor elements include a driving mass which performs movement solely in relation to the first axis; and a force conveying arrangement for conveying a static force effect between the substrate and at least one of the sensor elements, wherein the static force effect corresponds to a torque with respect to a third axis that is essentially perpendicular to the surface of the substrate.
