Patent attributes
The present invention relates to measuring devices used in measuring angular velocity and, more specifically, to oscillating micro-mechanical sensors of angular velocity. In the sensors of angular velocity according to the present invention, at least one pair of electrodes is provided in association with an edge of a seismic mass (1), (9), (10), (20), (30), (31), which pair of electrodes together with the surface of the mass (1), (9), (10), (20), (30), (31) form two capacitances such, that one of the capacitances of the pair of electrodes will increase and the other capacitance of the pair of electrodes will decrease as a function of the angle of rotation in the primary motion of the mass (1), (9), (10), (20), (30), (31). The structure of a sensor of angular velocity according to the present invention enables reliable and efficient measuring particularly in solutions for compact oscillating micro-mechanical sensors of angular velocity.
