To improve the sensor's output voltage sensitivity, two cymbals piezoelectric transducer are employed as the sensitive elements to form a differential cymbal piezoelectric vibration acceleration sensor. The structural features of the sensor are analyzed, second-order system mathematical model is established and the output voltage sensitivity of the sensor is also studied. The experimental results show that output voltage sensitivity of differential cymbals piezoelectric vibration acceleration sensor is two times of that of the sensor with single cymbal transducer. The experimental data agrees well with the theoretical analysis result.
