Piezoelectricity () is the charge that accumulates in certain solid materials ( notably crystals, certain ceramics, and biological matter such as bone, DNA and various proteins ) in response to applied mechanical stress.

Piezoelectricity is found in useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultrafine focusing of optical assemblies.

Piezoelectricity is the combined effect of the electrical behavior of the material:

* Piezoelectricity is the dual of piezomagnetism.

Piezoelectricity was discovered in 1880 by French physicists Jacques and Pierre Curie.

Piezoelectricity was discovered by Jacques and Pierre Curie in 1880.

Piezoelectricity may then manifest in a variation of the polarization strength, its direction or both, with the details depending on 1. the orientation of P within the crystal, 2. crystal symmetry and 3. the applied mechanical stress.
