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
