 sensitivity of piezoelectric transducer

                      sensitivity of piezoelectric transducer


 According to the static analysis, it is necessary to improve the sensitivity of the piezoelectric transducer by improving the sensitivity of the piezo crystal plate various components, that is, to improve the elasticity of the mechanical system, the equivalent constant of the piezoelectric ceramic plate voltage generator and the magnification of the measuring line. The potential for the constant of a piezoelectric ceramic is greatest.
According to the dynamic analysis, the sensitivity of the piezoelectric sensor should be combined with the frequency of external force to consider. In the range of amplitude-frequency characteristics, the sensitivity of the rectangular piezo element  piezoelectric sensor can be improved by increasing the quality of the mechanical system, increasing the piezoelectric constant of the piezoelectric ceramic and reducing the stiffness coefficient of the mechanical system and measuring the feedback capacitance of the line.
Combined with static analysis and dynamic analysis, Increasing the piezoelectric constant of piezoelectric ceramic can effectively improve the sensitivity of piezoelectric sensor, and it is also one of the most practical methods. This is because it is possible to more easily improve the constant of the piezoelectric ceramic by adjusting the chemical composition of the piezoelectric ceramic. And the piezoelectric ceramic can improve the effective  constant of the piezoelectric ceramic by selecting the appropriate vibration mode and series-parallel.
