Piezoelectric ceramic sheets are functional ceramic materials that can convert mechanical and electrical energy into each other. The so-called Piezoelectricity refers to that when some medium is subjected to mechanical pressure, even if the pressure is small enough to sound vibration, it will produce compression or elongation and other shape changes, making the surface of the medium charged. This is the positive Piezoelectricity. On the contrary, when an exciting electric field is applied, the medium will produce mechanical deformation, which is called the inverse Piezoelectricity.
