Abstract:
1. An oscillating micro-mechanical sensor of angular velocity, said sensor comprising: two seismic masses which are attached to the body of a sensor component at support areas; a connecting spring between the seismic masses, such that a primary motion of the sensor of angular velocity, which motion must be generated, is an opposite phase angular oscillation of the two seismic masses about the support areas; and at least on bending spring which connects the seismic masses, said at least one bending spring mechanically synchronizes the primary motion of the seismic masses, and that the seismic masses are connected to the support areas by at least one of springs and stiff auxiliary structures, which give the seismic masses a degree of freedom in relation to an axis of rotation perpendicular to the plane of the disk formed by the seismic masses, and in relation to at least one axis of rotation in the direction of the plane of said disk.
