Piezoelectricity

Piezoelectricity is the charge which accumulates in certain solid materials (notably crystals, certain ceramics, and biological matter such as bone,DNA and various proteins)^[1] in response to applied mechanical strain. The word piezoelectricity means electricity resulting from pressure. It is derived from the Greek piezo or piezein (πιέζειν), which means to squeeze or press, and electric or electron (ήλεκτρον), which stands for amber – an ancient source of electric charge.^[2] Piezoelectricity is the direct result of the piezoelectric effect.
