The properties of piezoelectric ceramic sheets mainly include piezoelectric constant, dielectric constant, mechanical quality factor, and resistivity. Among them, the piezoelectric constant represents the electric field intensity generated by the piezoelectric ceramic sheet under unit stress, and is one of the most important properties of the piezoelectric ceramic sheet. The dielectric constant represents the polarization intensity generated by a piezoelectric ceramic sheet under the action of a unit electric field intensity, which is closely related to the piezoelectric constant. The mechanical quality factor represents the ratio of mechanical loss to energy storage of piezoelectric ceramic sheets and is an important parameter for evaluating their performance. Resistivity represents the conductivity of piezoelectric ceramic sheets, and low resistivity is necessary for high-frequency applications.
