Research on the Bending Effect of Piezoelectric Quartz

摘要：

The bending effect of piezoelectric quartz is investigated by the theories of elasticity and electromagnetism. First the bending stress is deduced using mechanics of material. According to piezoelectric equation the volume and surface bound charge densities by bending are calculated. Using Finite Element Method, the distribution of the electric field in quartz bar is simulated. Based on the theoretical analysis, to measure the electric effect by bending the two detection electrodes are effectively arranged on the surfaces of the quartz bar. The theoretical and experimental results both show that the polarization charge is linear with the bending moment. The research on the bending effect of piezoelectric quartz will provide a new method for piezoelectric micro actuator.
