An oscillator crystal has two electrically conductive plates, with a slice or tuning fork of quartz crystal sandwiched between them.
Modeling Electrical model A quartz crystal can be modeled as an electrical network with a low- impedance (series) and a high- impedance (parallel) resonance points spaced closely together.
In clocks and watches The quartz crystal that serves as the timekeeping element in modern quartz clocks and watches (right) is in the form of a tiny tuning fork.
Here, an oscillating quartz crystal is immersed into a fluid and the specific influence on the oscillating behavior defines the viscosity.
In 1968, Juergen Staudte invented a photolithographic process for manufacturing quartz crystal oscillators while working at North American Aviation (now Rockwell ) that allowed them to be made small enough for portable products like watches.
Piezoelectric pickups use a "sandwich" of quartz crystal or other piezoelectric material, typically placed beneath the string saddles or nut.
