Study on the Influence of Multi-piezoelectric Effect on Performances of Piezoelectric Sensor

摘要：

This paper analyzes that the affection of multipiezoelectric effect on performances of piezoelectric sensor including elastic constants, Poisson ratio, piezoelectric coefficient and energy conversion so on. The secondary converse piezoelectric effect by the beginning of the first positive piezoelectric effect decreases the deformation of piezoelectric sensor, elastic constants, energy of force-electric conversion and change Poisson ratio at the same time; the third positive piezoelectric effect decreases piezoelectric coefficient of piezoelectric sensor. This investigation of multi-piezoelectric effect on performances of piezoelectric sensor will provide the new method to improve sensitivity, force-electric conversion ratio and convertible precision.
