The result: a form of PVDF that displays the intriguing property of piezoelectricity (from the Greek word "piezein," meaning to press), first reported in crystals such as quartz and sodium chloride in the early 1880s by Pierre Curie and his brother Jacques.
Thus, stretching provides us a new method to generate the [gamma]-form structure of potential piezoelectricity and ferroelectricity.
Piezoelectricity is a well-known effect in which stretching or compressing a material causes it to generate an electrical voltage (or the reverse, in which an applied voltage causes it to expand or contract).

Piezoelectricity is the phenomenon whereby certain materials produce an electric charge when the material is under stress.
Piezoelectricity is the accumulation of a charge in a solid in response to mechanical stress.
