    摘要： A sensor includes a substrate having a first electrode arrangement; a first mass oscillator having (a) a first mass, (b) a first mass centroid, and (c) a second electrode arrangement including a first area centroid coinciding with the first mass centroid; and a second mass oscillator having (a) a second mass equal to the first mass, (b) a second mass centroid coinciding with the first mass centroid, and (c) a third electrode arrangement including a second area centroid coinciding with the first area centroid. Areas of the second and third electrode arrangements are equal. The sensor detects respective rotation rates around axes parallel to and perpendicular to a substrate extension. The oscillators are oscillatorily connected to each other and to the substrate, are deflectable, and experience respective forces in the directions of extension of the axes upon respective rotations around the other of the axes.

    摘要： A yaw-rate sensor having a substrate and a plurality of movable substructures that are mounted over a surface of the substrate, the movable substructures being coupled to a shared, in particular, central spring element, means being provided for exciting the movable substructures into a coupled oscillation in a plane that extends parallel to the surface of the substrate, the movable substructures having Coriolis elements, means being provided for detecting deflections of the Coriolis elements induced by a Coriolis force, a first Coriolis element being provided for detecting a yaw rate about a first axis, a second Coriolis element being provided for detecting a yaw rate about a second axis, the second axis being oriented perpendicularly to the first axis.
