Piezoelectric energy is another type of green energy. It comes from the word “piezo,” which means “to press” in Greek. This form of energy is produced when certain materials are squeezed, pressed, or vibrated—and they respond by generating an electric charge.
Some examples are quartz crystals, ceramics, and certain types of plastics which have a special property. When you apply pressure or movement to them it creates electricity.This electricity is usually very small, but it can be collected and used .
Some Uses of Piezoelectric Energy are-
Smart Floors- Floors in busy places (like train stations or malls) can have piezoelectric tiles.
-
- As people walk over them, the pressure from footsteps creates electricity!
- This energy can be used to light signs or charge small batteries.
Dance Floors-
- Some nightclubs have dance floors that power lights with the movement of dancers.
- Roads and Highways (Experimental)
- Cars driving over special roads can produce energy to power streetlights or sensors.
- Wearable Technology
- Shoes or clothing can be made with piezo materials to generate electricity as you move—maybe even to charge your phone someday!
- Medical Devices
- Tiny piezoelectric materials can power small medical implants using the body’s movements.
