Crystals can be used for electricity through the method of piezoelectric (mechanical energy discharge), of which quartz is a typical example. When the crystal is fixed and subjected to direct force by a permanent magnet, a certain amount of electricity can be released and detected. The piezoelectric method is widely applied in cigarette lighters and
The curie’s simple experiment in the 19th century involving basic items like tinfoil, glue and a saw lead to the discovery of Piezoelectricity which unleashed the age of modern sensor technologies. The basic principle of mechanical stress inducing electric current was realized by two materials, namely crystals along with ceramics.
