1. PIEZO ELECTRIC ENERGY
HARVESTING SHOES

2. Piezoelectricity (also
called the
piezoelectric effect)
is the appearance of
a voltage across the
sides of a crystal
when you subject it
to mechanical stress
What is a piezo?!

3. WORKING OF PEIZOS
1.Normally, the charges in a piezoelectric
crystal are exactly balanced, even if they're
not symmetrically arranged.
2.The effects of the charges exactly cancel
out, leaving no net charge on the crystal
faces.
3.If you squeeze the crystal , you force the
charges out of balance.
4.Now the effects of the charges (their
dipole moments) no longer cancel one
another out and net positive and negative
charges appear on opposite crystal faces. By
squeezing the crystal, you've produced a
voltage across its opposite faces—and that's
piezoelectricity!

6. Unaffected by external electromagnetic fields.
Pollution Free
Low Maintenance
Easy replacement of equipment.

7.  Piezoelectricity is a revolutionary source for
“GREEN ENERGY”.
 Flexible piezoelectric materials are
attractive for power harvesting applications
because of their ability to withstand large
amounts of strain.
 Convert the ambient vibration energy
surrounding them into electrical energy.
 Electrical energy can then be used to power
other devices or stored for later use.
