Some materials, such as certain ceramics and quartz crystals, can produce electricity when placed under mechanical stress. The ability to convert voltage to and from mechanical stress is called piezoelectricity. Quartz crystals maintain a precise frequency standard, which helps to regulate the movement of a watch or clock, thus making the timepieces very accurate. Quartz is also used in radios, microprocessors, and many other technological and industrial applications.
