Digital angular velocity detection device

A digital angular velocity detection device, including a stator formed on a substrate. A rotor operable to rotate in response to an inertial force is provided. The rotor has a plurality of electrodes formed at regular intervals on a curve at a predetermined radius away from a center of the rotor. A detector having detection electrodes facing the plurality of electrodes is provided. The detection electrodes are operable to detect a rotation angle of the rotor based on a number of electrostatic capacitance variations generated between the plurality of electrodes and the detection electrodes.
