Description
Quartz is a mineral that was discovered by the Frenchman Pierre Curie and his brother (Jacques), who was studying a sample of sand in the year 1880 when they observed a strange phenomenon. It is that when quartz (silicon dioxide) is exposed to a mechanical voltage, an electric current is generated. Conversely, if the quartz crystal is exposed to an electric field, it will oscillate and vibrate at a certain frequency. It was also found that this vibration and oscillation were of high regularity and accuracy. This phenomenon, which was known as piezoelectric, enabled researchers to manufacture many sensitive devices. Among the most important are watches designed to measure time with high accuracy, as the share of quartz in the watch industry has reached more than 85% of the global watch market.
