with quartz being one of the main crystals they focused on. Piezoelectricity first proved its utility in World War I, with submarine warfare and the need for ultrasonic transducers for sonar.

Piezoelectricity—a crystal can generate a tiny electric charge when its atomic structure is squeezed strong enough—occurs in many minerals but is particularly strong in quartz. What if this ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge ... resulting in mechanical deformation. Quartz is ...
