摘要:
A gyroscope of the present invention includes a tuning fork having three legs and a support portion, an upper glass substrate and a lower glass substrate, between which the tuning fork is interposed, driving electrodes respectively arranged on the two glass substrates so that the driving electrodes are opposed to a base portion of each leg, six movable protruded detection electrodes formed on each of the top surface of and the underside of an end portion of each leg, and six stationary detection electrodes on each of the upper and lower glass substrates so that the six stationary detection electrodes are respectively opposed to the six movable detection electrodes. The gyroscope of the present invention thus features compact design, high sensitivity, and low required driving voltage.
