Quartz Piezoelectrics
Piezoelectric materials are best described as materials that either generate an electric charge when deformed, by hitting or bending, or change their shape when an electric charge is applied to them. As such, they are one of the most prolific technologies in the growing area of smart materials, particularly in the area of energy harvesting. This mechanical strain at the heart of the technology can come from many different sources, but to illustrate the principle, placing a ruler on the edge of a desk and pinging it is a good example of the piezoelectric effect. If the ruler were made of piezoelectric material the vibration would produce electricity, which when attached to a light source will generate light.
The idea of piezoelectric ...
