1. Product description


Piezoelectricity is a type of electricity that occurs when materials possessing piezoelectric properties are exposed to pressure or stress. Examples of these materials are ceramics, also called piezoceramics , and crystals.

Piezoelectric Ceramics (piezoceramics), such as Piezoelectric Ceramic Ring, Piezoelectric Ceramic Disc, Piezoelectric Ceramic Tube, Piezoelectric Ceramic Ball/Hemisphere, Piezoelectric Ceramic Cylinder and Piezoelectric Ceramic Square/Rectangular.
