POWER GENERATING SYSTEM BY
FOOTSTEP

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.

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.

 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.

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.
