Abstract
An angular rate sensor for detecting a rotation includes 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. 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 will not cause any significant radial movement of the detecting element/s or the oscillating elements. Also disclosed are different methods for operating said sensor.
