Speed of sound piezoelectric ceramic. It is derived from the greek word πιέζειν. At low electric fields piezoelectric ceramics are well described by the linear piezoelectric. Piezoelectric ceramics are perovskite varieties in which the linear piezoelectric response dominates. Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals certain ceramics and biological matter such as bone dna and various proteins in response to applied mechanical stress the word piezoelectricity means electricity resulting from pressure and latent heat.
