The Piezoelectric Effect Some of the crystals are piezoelectric, for example quartz. An electric charge can be produced when these crystals are compressed or hit. And if an electric current is applied on these piezoelectric crystals, their shape can be altered accordingly. The piezoelectric property provides these special crystals possibilities for usages in many fields.
What causes piezoelectricity ? Piezoelectricity is formed when the only ion in the cage of atoms is deformed or put under electric field. There are atomic structures that contain a cage that has atoms. Among the many atoms in this cage, there is one ion that is semi-mobile. This ion has a stable state. However,
