Piezoelectric ceramic

A man-made piezoelectric material in which the piezoelectric properties must be induced by poling. Piezoelectric ceramics are used in transducers. Details ...

Also commonly referred to as "ceramic" or, preferably, "piezoceramic". (Note — For convenience, this site generally refers to all piezoelectric materials as "piezoceramic", even if they are not actually ceramics — e.g., quartz. )
