2. INTRODUCTION
Walking is the most common activity in
human life.
The energy lost by walking can be
tapped and converted into electrical
energy.
This energy produced will be the
alternative source of energy.
3. NEED OF THE SYSTEM
The demand of power is increasing
day by day but the generation of
power is insufficient.
The utilization of waste energy of
foot power with human motion is very
important for highly populated
countries like India.
In India, there are still many villages
with no electricity.
So the footstep power generating
system will be helpful to develop the
economy of the nation.
4. BASIC PRINCIPLE
The basic principle of the system is piezoelectric effect.
According to which the ability of certain materials to convert
mechanical force in to the electrical force.
By this principle, we are using a piezoelectric sensor which
converts pressure into electrical power.
6. Whenever force is applied on piezoelectric crystals that
force is converted into electrical energy.
This energy is stored in the lead acid battery which is
connected to the inverter.
This inverter converts 12 volt DC into 230 volt AC.
We are using rechargeable battery for giving supply to the
system.
The microcontroller AT89S52 is used to display the
amount of battery get charged using a LCD.
This 230 volt AC voltage is used to activate the loads.
WORKING
7. POWER GENERATING IN FOOTSTEPS
This method is responsible for
generation of large amount of
energy.
This system is placed at the
footpaths and steps where
people make contact with it.
These materials get excessive
pressure and force.
By this greater amount of energy
is generated and stored.
8. ADVANTAGES
