Abstract
Embodiments of the invention relate to measuring devices used in measuring angular velocity and, more precisely, to vibrating micro-mechanical sensors of angular velocity. The sensor of angular velocity according to an embodiment of the invention is adapted to measure angular velocity in relation to two or three axes, and at the least two seismic masses (---) of the sensor of angular velocity are adapted to be activated into primary motion vibration by a common mode. The structure of the sensor of angular velocity according to the invention enables reliable measuring with good performance, particularly in small size vibrating micro-mechanical sensors of angular velocity.
