Piezoelectricity is the ability of certain materials to generate an electric charge in response to mechanical stress, such as squeezing or pressing. This phenomenon occurs because the crystal structure of piezoelectric materials can produce electric polarization when subjected to mechanical deformation, leading to the generation of an electric field.
what is the amount of voltage that is generated by a piezo disk of quartz with a polarization coefficient of 3*10^-12
Squeezing your but will not make it bigger.
It is mostly caused by pressing the insert key, try pressing it again, or reset computer.

The phenomenon of piezoelectricity was first discovered by the Curie brothers, Pierre and Jacques, in 1880. They observed that certain crystals produce an electric charge when physically stressed or deformed.
Examples: tourmaline, quartz, Rochelle salt, topaz etc.
The quality of bones that allows them to deform slightly and vibrate when electrical currents pass through is known as piezoelectricity. Piezoelectricity refers to the ability of certain materials, like bones, to generate an electric charge in response to mechanical stress or pressure. This phenomenon helps bones to respond to and adapt to mechanical forces, such as those experienced during physical activity.
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.
