Patent ID: 8342022

Claim:
A micromechanical rotation rate sensor comprising: a substrate; a base element that comprises an inertial mass; plural spring elements that movably connect and suspend said base element relative to said substrate; an excitation arrangement that is arranged and cooperates with said base element so as to be adapted to excite said base element into oscillation in an oscillation direction in an oscillation plane; and a read-out arrangement that is arranged and cooperates with said base element so as to be adapted to sense a motion of said base element in at least one sensing direction perpendicular to said oscillation direction; wherein each one of said spring elements has at least one bend respectively at at least one vertex point; and wherein said spring elements are so configured and arranged such that in connection with said oscillation of said base element in said oscillation direction in said oscillation plane said at least one bend deflects perpendicularly to said oscillation plane while said base element is not excited to deflect perpendicularly to said oscillation plane.
