Rsp50 Pzt8 50*20*5 Piezoelectric Ceramic Ring 50mm for Ultrasonic

What is the piezoelectric ceramic?
The characteristic of converting mechanical energy to electrical
energy, and from electric energy to mechanical energy is called
piezoelectric. That is to say, when the piezoelectric ceramics are subjected to a voltage, they will expand or contract.
Generally, ceramics consist of crystals. Each crystal is made up of
atoms with a positive or negative electrical charge. Most ceramics
have positive and negative electric charges. But even under natural
conditions, some dielectric ceramics in the crystals have
unbalanced positive and negative electric charges, resulting in
biased electric charges (spontaneous polarization).
If the polarizing process is applied to ferroelectric ceramics,
piezoelectric ceramics are produced. When applying an AC voltage to the piezoelectric ceramics, the external electric charges will attract
or repel the centers of the positive and negative electrical
charges in the ceramics, causing the ceramics to expand or contract.
