WHATIS PIEZOELECTRICITY?Electricity resulting from
applied mechanical stress on aspecial type ofmaterial(piezoelectric material)is called piezoelectricity.

AMOUNT OF VOLTAGE INDUCED
Amount of voltage produced is directly proportional
to:-
1) Stress Applied
2) Fluctuation of Stress3) Area of crystal

When mechanical stress is applied on shoe bywalking, piezoelectric crystal gets activated.
The Voltage will get induced and the diode willrectify the output voltage.
The induced voltage will pass through chargingcircuit, which is connected to female type USBconnector.
The phone can be charged by connecting USB
cable to USB port in shoe.

INERESTING PROPERTY OF
PIEZOELECTRIC MATERIAL
According to the concept, voltage can be induced
by applying mechanical stress, but reverse is also
possible, i.e. when we apply voltage to the
piezoelectric crystal mechanical strain get induced
in the crystal.
A change in dimensions can be induced by the
application of a voltage to a piezoelectric material.
In this way they are very similar to electrostrictive
materials.

BENEFITS
We walk nearly 3000 steps per day, if the average
mass of person is 60 kg then it is enough to charge
a phone battery up to full.
We can use it without requirement of any external
aid.
It is not costly.
Also helpful in acupressure therapy.
Benefitted to people of remote and rural areas. Soldiers can be greatly benefitted from power
generating shoes,as it can be good alternative for
power source.

COST ANALYSIS
We can prepare the shoe with reasonable amount
of expenses.
Cost of parts
Pair of shoes-----Rs 500 Piezoelectric shoes(for one shoe)----Rs200
Diodes----Rs50
Wires-----Rs20
Soldering----Rs20 Miscellaneous----Rs10
Total---------Rs 800
