Question

_______is an example of piezoelectric material.
1. Glass
2. Quartz
3. Corundum
4. Neoprene

Answer 1

Correct Answer - Option 2 : Quartz

Piezoelectric materials:

• Materials that produce electric energy when they are placed under mechanical stress.
• The piezoelectric process is also reversible, so if we have supplied electrical energy to these materials, they will actually change shape slightly.

Piezoelectric materials are classified into two groups:

Natural	Synthetic
Quartz	Ammonium Dihydrogen Phosphate (ADP)
Rochelle sod	Lithium Sulphate
Tourmaline	Potassium Tartrate
