[[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. It is derived from the Greek piezo or piezein, which means to squeeze or press, and electric or electron, which means amber, an ancient source of electric charge. | [[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 action of piezoelectricity in Topaz can probably be attributed to ordering of the (F,OH) in its lattice, which is otherwise centrosymmetric: Orthorhombic Bipyramidal (mmm). Topaz has anomalous optical properties which are attributed to such ordering. | The action of piezoelectricity in Topaz can probably be attributed to ordering of the (F,OH) in its lattice, which is otherwise centrosymmetric: Orthorhombic Bipyramidal (mmm).

* Viral proteins, including those from bacteriophage. One study has found that thin films of M13 bacteriophage can be used to construct a piezoelectric generator sufficient to operate a liquid crystal display. | * Viral proteins, including those from bacteriophage.
