Abstract (en)
[origin: WO2005098358A2] The invention relates to an angular rate sensor for detecting a rotation. Said sensor comprises the following components: a substrate, at least one oscillating element that can be excited so as to oscillate rotationally or radially, an anchor structure, one or several detecting elements, one or several joining elements that connect the detecting element/s to the oscillating element, a mechanism for exciting the oscillating element, and a device for detecting a radial or rotational oscillation of the detecting element/s. The inventive angular rate sensor is characterized in that each of the detecting elements can oscillate radially on the same plane on which rotational oscillation of the oscillating element occurs, or vice versa, while the centrifugal force Fz caused by the rotational oscillation can trigger substantially no radial movement of the detecting element/s or the oscillating element/s. Also disclosed are different methods for operating said sensor.
