Piezoelectric crystal is used in which device?
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.
What is the cost of a piezoelectric crystal?
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.
Explain the working of piezeoelectric oscillator?
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.
What are oscillator crystals made out of?
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~
What two types of ways the droplets of ink are formed in inkjet printers?
piezoelectric crystal vibration generates pressure that ejects ink through the nozzleresistive pulse heater vaporizes a tiny amount of the water in the ink and steam pressure ejects ink through the nozzle
How do you pronounce piezoelectric crystal?
Like this: (piezoelectric-crystal)
What happens to a piezoelectric crystal when it is squeezed?
When you squeeze a piezoelectric crystal, electricity forms. This is helpful in products such as watches, microphones, computers, and gas grills.
What is the cost of small piezoelectric crystal?
around 100
Could you ignite gunpowder with a piezoelectric crystal?
Yes.

What is piezoelectric crystal?
Piezoelectricity is the property of a material to generate movement from an electric current, and vice versa. A common piezoelectric material is quartz.
What is the surface area of piezoelectric crystal?
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.
What does the squeezing from pressure do to the rocks crystal grains?
This is called piezoelectric. The pressure causes an electric charge.
Basic principle for the piezoelectric accelerometer?
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.
What happens to piezoelectric crystals when subjected to constant and consistent pressure?
they form a new type of rock or crystal.
Name the device that converts non electrical quantity to an electrical signal?
-- microphone -- piezoelectric crystal -- dynamo
What is the function of piezoelectric 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.
