<emphasis role="bold">Piezoelectric Materials</emphasis> Piezoelectric materials produce an electrical voltage when they are subjected to mechanical stress or deformation, and their dimensions change when they are subjected to an electric field. On the microscopic level, the structure of a material normally consists of uncharged randomly arranged dipoles. In a piezoelectric material, the dipoles are arranged along a single axis. When the material is subjected to a mechanical stimulus, such as stress or deformat…
