Abstract: This paper proposes the modified mechanical and mathematical modeling of lead zirconium titanate (PZT) sensor based on the PZT constitutive relation in order to solve the complicated boundary condition and stress situation of PZT sensor due to the effect of adhesive-layer damping. The experimental study on the surface-bonded PZT sensor is chosen to carry out the correctness of the proposed models. The results show that the PZT sensor modeling is simplified to three types. When the amplitude of harmonic force is constant, the greater the excitation frequency, the more sensitive the output voltage is, the easier the signal acquisition is. At a certain frequency, the voltage output is proportional to the force amplitude. The larger the area or thickness of PZT, the greater the output voltage is, the more sensitive the signal output is. The output voltage is in quadratic relation to the bonding thickness. Furthermore, the smaller the output voltage, the greater the damping is. The signal loss is about 25.82%. The signal acquisition effect of the PZT square wafer is better than that of circular wafer under the same area of PZT sensor. The research achievements reveal the sensing mechanisms and validate the efficiency of the developed model and effectively simulate and detect direct piezoelectric rule of PZT sensor.
