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.
Why is quartz used in piezoelectric transducer?
Quartz is used in piezoelectric transducers because of potential for high voltage input and acoustic power. Quartz is a piezoelectric crystal and when it is mechanically strained or deformed by stress, electric charges appear on some surfaces. When the strain is reversed, the polarity of the charges reverse. This allows vibration of quartz crystals to be transformed into electric pulses.
What are piezoelectric substances?
peizo electric substances are those substances which when placed in a uniform magnetic field then it lies perpendicular to the magnetic field.
Which phenomenon generates electric current?
A potential difference (electromotive force) does.
Can piezo electric crystal generate electricity?
yes. piezoelectric crystals can convert mechanical energy (applying physical force) to electrical energy, and vice versa. however, this is a very tiny amount of electricity.

What happends when an electric current passed through a piezoelectric crystals?
They physically change shape.

Are there any materials that undergo strong contraction when an electric current is introduced?
Yes, all piezoelectric materials exhibit the reverse piezoelectric effect. A piezoelectric material is one that generates an electric field or electric potential in response to applied mechanical stress. Therefore, in the reverse case, passing an electric current through the material or an electric potential across the material, will cause it to contract or elongate, depending on the direction of the current. One of the best example of this is lead zirconate titanate which will contract/elongate up to about 0.1% of the original dimensions.
What does the squeezing from pressure do to the rocks crystal grains?
This is called piezoelectric. The pressure causes an electric charge.
How does piezoelectric produce electric current?
When piezoelectricity material is squeezed, it produces electricity. This is the esseantial idea about piezo materials.
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 are piezoelectric substances?
peizo electric substances are those substances which when placed in a uniform magnetic field then it lies perpendicular to the magnetic field.
Which phenomenon generates electric current?
A potential difference (electromotive force) does.
Can the energy converted by peizo electric transducers be stored?
Yes. A piezoelectric transducer converts stress (pressure) into electrical energy. You can store electricity in a battery or capacitor.
How do you convert laser energy to electrical energy?
By using photo electric emission phenomenon.
What kind of phenomenon happens in the area immediately around an electric current?
Magnetic field
