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.
Piezoelectric materials are special materials. When stress is applied to them, they produce electric voltage. Piezoelectric materials are commonly in the form of ceramics ( piezoceramics ) and crystals. They are used in many ways. In daily life, they are used as igniters in gas grills, gas stoves, and cigarette lighters. They are also used
