The vast majority of devices that use piezoelectric crystals (piezoelectric buzzers, fish finders, atomic force microscopes, etc.) use crystals of lead zirconate titanate (PZT).
The crystal oscillator in a computer or digital clock uses the piezoelectric effect, but it is usually made of pure quartz (silicon dioxide).
Many different crystals and other materials exhibit the piezoelectric effect, including quartz crystals, cane sugar, and bone.
The price varies widely depending mostly on how precisely it must be cut for its function and the quantity produced (i.e. law of supply and demand).
The vast majority cost only a few dollars or less.
For precision frequency standards however the cost can in the $1000 range sometimes, due to the ultraprecise cut needed.
The piezoelectric crystals used in gas ignitors (e.g. propane grills, butane candle lighters) are particularly inexpensive as they have no requirement for precision cutting and are made in very very large quantity.
The piezoelectric crystal is used in transducers in ultrasound medical imaging. The crystal vibrates when an electric field is applied to it, the oscillations of the crystal vibrating occurs at very high frequencies beyond the threshold of human hearing.
A piezo-electric material is one who's physical dimensions (size) noticeably change when a current is passed through it. So if an AC (alternating current) is passed through a piezo-electric material, it itself alternates, or oscillates. This type of material is exploited in Electron Microscopes and Atomic Force Microscopes, which is how they are able to get such small, yet precise images.
Any where a stable desired frequency is needed. Crystal Oscillators are quite accurate, they are used in computers as well as wrist watches.They use a mechanical oscillatory force that is induced by an electric charge on a piezoelectric substance at resonance.en.wikipedia.org/wiki/Piezoelectricity~MECHASUN~

Piezoelectric materials have been integrated with silicon microelectromechanical systems (MEMS) in both microsensor and microactuator applications. Some recent and emerging applications of piezoelectric MEMS are acoustic emission microsensors, vibration monitors, molecular recognition biosensors, precision positioners, micropumps, and linear stepper motors. - See more at: http://www.chacha.com/question/how-are-piezoelectric-materials-that-contain-silicon-used-in-science-and-industry#sthash.EpLIkFTw.dpuf

When you squeeze a piezoelectric crystal, electricity forms. This is helpful in products such as watches, microphones, computers, and gas grills.

Piezoelectricity is the property of a material to generate movement from an electric current, and vice versa. A common piezoelectric material is quartz.
All the (pairs of ) surfaces of a piezoelectric crystal do not have the same piezo properties. And the temperature coefficient also alters at different angles through the crystal. So commonly, the 'BT' cut is the one with the lowest temperature coefficient.
This is called piezoelectric. The pressure causes an electric charge.
Piezoelectric is natural, as acceleration is directly proportional to force. In a piezoelectric accelerometer, charge accumulates on the crystal and is translated and amplified into either an output current or voltage, so this only respond to AC phenomenon such as vibration or shock.
they form a new type of rock or crystal.

Piezoelectric crystals have unique properties. If you strike them (not too hard), they produce a high voltage pulse. If you apply electricity to them, they swell. If you just tag them with a pulse of electricity, they ring at their modal frequency. These properties allow them to be used in many applications. The following are just a couple examples of their use. Disposable lighters that don't have flint use a piezoelectric crystal to generate an arc that ignites the gas. Accelerometers use piezoelectric crystals to generate signals proportional to how fast something is accelerating. In electronics, piezoelectric crystals are used to generate master timing signals.
