Piezoelectricity is a compound word derived from the Greek language for pinching and amber. This etymological description is helpful if you could imagine generating an electric charge by applying a squeezing action to a block of material (not necessarily amber as this isn't a known piezoelectric material), the electricity generated being dependent on; the amount of force used in compressing or deforming the material, the amount and type of deformation of the material's crystal structure and the speed or frequency of compressions or vibrations to the material.

Piezoelectricity is more frequently defined as the electrical polarization of materials due to the
application of mechanical stresses or strain.
Generation of electricity from compressive mechanical forces is certainly interesting. With the
exception of chemical primary batteries, electricity has always been generated by mechanical
means by the relative motion of magnets and coils in dynamos for example. Piezoelectricity is
unique in that allows the generation of electricity from what can be considered waste sources of
mechanical forces; such as the footsteps of pedestrians on a bridge, the rattling of leaves in the
wind, or on roads as cars drive by and even in the shock absorber springs of vehicles.
