3. PIEZO ELECTRIC EFFECT
Piezoelectricity was discovered in 1880 by Pierre and Paul-Jacques Curie, who found that when they compressed certain types of crystals including quartz, tourmaline, and Rochelle salt, along certain axes, a voltage was produced on the surface of the crystal. This effect is known as piezoelectric effect.

White quartz

4. PIEZOELECTRIC GENERATORS
Piezoelectric generator is nothing but a piezoelectric crystal sandwiched between two metallic electrodes . So when the mechanical pressure/stress is applied on the crystal ,emf is generated.

Lower Metallic plate

5. IMPORTANCE
This effect is exploited in a variety of practical devices such as microphones, phonograph pickups, and wave filters in telephone-communications systems and for electric power generation etc .ex

6. IMPORTANCE
The converse effect is also possible i.e when the emf is applied along certain electrical axes in the crystal ,this crystal produces mechanical vibrations . This effect is used in some variety of practical devices such as buzzers, ultra sonic filters and sonar for the production of U.S waves. ex

7. PIEZOELECTRIC CAR
This car is made up of piezoelectric tires. These tires are equipped with piezoelectric cables, these cables consist of piezoelectric generators.So when the tires are rotated on the road, pressure is applied on the tires continuously. Then they generate electricity.

9. ADVANTAGES OF THE CAR
The batteries in this car are self charged as the car is in motion.It is due to the power generated by the tires. So only onetime external charging is enough.
By using Lead zirconate piezo crystal we can generate until volts by small deformations of the tire.
Eco friendly i.e, it does not pollute the environment.
