Patent ID: 8479575

Claim:
A microgyroscope for determining rotational movements about an x-axis and/or a y-axis, and a z-axis, the microgyroscope comprising: a substrate; a plurality of oscillating masses comprising individual masses arranged around a central point on the substrate; a plurality of springs for fastening the plurality of oscillating masses to the substrate; a plurality of drive elements for inducing radial oscillation of the individual masses on an x-y plane, with respect to the central point, in order to generate Coriolis forces when the substrate rotates; and a plurality of sensor elements for registering deflections of the individual masses caused due to the generated Coriolis forces; wherein the individual masses are arranged in two groups comprising a first group and a second group, the masses of both groups being jointly induced by the plurality of drive elements to perform an oscillating primary movement in the x-y plane, the masses of the first group being arranged on the substrate so as to allow movements out of the x-y plane, the masses of the second group being arranged on the substrate so as to allow movements perpendicular to the oscillating primary movement in the x-y plane.
