Piezoelectric materials offers us a gift of nature. Convert electrical energy to sound waves. Thanks to these properties are used for non-destructive inspection methods. piezoelectric materials give electricity resulting under pressure. Piezoelectric materials are divided into two groups: those based on ceramics and crystals. The most well-known piezoelectric material is silicon di oxide.
