Piezoelectricity is the ability of some materials (notably crystals and certain ceramics , pincluding bone to generate an electric field or electric potential in response to applied mechanical stress. The effect is closely related to a change of polarization density within the material's volume. If the material is not short-circuited , the applied stress induces a voltage across the material. The word is derived from the Greek piezo or piezein, which means to squeeze or ress.

Piezoelectricity is the property of a material to generate movement from an electric current, and vice versa. A common piezoelectric material is quartz.
piezoelectricity - the principle by which certain crystals become electrically charged when pressure is applied.

piezoelectricity
consider a triangle where each corner represents kinetic, electrical n thermal. the side bw thermal and electrical rep the pyroelectricity and it produces no kinetic The side bw thermal and kinetic rep the piezoelectricity and it produces no heat
when crystals such as quartz and Rochelle salts are squeezed or pressed ,they release electrons.This effect is known as piezoelectricity.
You are talking about piezoelectricity. See related linksbelow.
When piezoelectricity material is squeezed, it produces electricity. This is the esseantial idea about piezo materials.
