Piezo-electric material converts mechanical energy into electrical energy.
A commonly known piezoelectric material is quartz.
Working principle of piezo-electric material
- A piezoelectric crystal is placed between two metal plates. At this point, the material is in perfect balance and does not conduct an electric current.
- Mechanical pressure is then applied to the material by the metal plates, which forces the electric charges within the crystal out of balance.
- Excess negative and positive charges appear on opposite sides of the crystal face.
- The metal plate collects these charges, which can be used to produce a voltage and send an electrical current through a circuit.
