A new multi-electrode quartz resonator and signal processing circuit is designed on the basis of analyzing the stress distribution in the wafer when the quartz wafer is subjected to force. When a plurality of resonators are simultaneously excited at room temperature and atmospheric conditions, the resonator’s linearity of force-frequency characteristics and frequency stability corresponding to the respective electrodes are excellent. After the interaction frequency difference and superposition processing to the frequency of each resonator, the force-frequency coefficient of the output frequency signal can reach 2 951.8 Hz/N, the linear correlation is 0.999 7, and the frequency stability can reach the magnitude of 10-10.
