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.
