2. For an alternative method to generate
electricity there are number of methods by
which electricity can be produced.
Out of such methods, foot step energy
generation can be an effective method to
generate electricity.
3. Dynamo:
A dynamo, originally
another name for an
electrical generator, i.e, a
generator that produces
direct current with the use of
a commutator.
Rack and pinion system:
A rack and pinion is a
type of linear actuator that
comprises a pair of gears which
Convert rotational motion into
linear motion.
4. 3. Rotary Converter
Development:
Used to develop
complex
multi-field single-rotor
devices with two or
more
commutators.These
were known as a rotary
converter.
5. LITERATURE REVIEW
An Investigation on Generation of Electricity Using Foot Step
Nowadays energy and power are the one of the basic necessities
regarding this modern world. As the demand of energy is
increasing day by day, so the ultimate solution to deal with these
sorts of problems is just to implement the renewable sources of
energy.
But these renewable energy sources must have to be adopted in
practical manner by keeping an eye on all aspects regarding the
research work. So then these techniques should be applied in
order to get the desired output.
The objective of this work is power generation through footsteps
as a source of renewable energy that we can obtained while
walking on to the certain arrangements like footpaths, stairs, plate
forms and these systems can be install elsewhere specially in the
dense populated areas.
6. Electromagnetic Foot Step Power Generation
The main aim of this project is to develop much cleaner
cost effective way of power generation method, which in
turns helps to bring down the global warming as well as
reduce the power shortages.
In this project the conversion of the force energy in to
electrical energy by using electromagnetic induction.
In this project the force energy is converted into
electrical energy.
The control mechanism carries the copper coil and bar
magnetic which is used to generate voltage, a
rechargeable battery is used to store this generated
voltage.
7. WORKING
When a human steps on the device
due to his/her body weight the iron
plate moves downwards and drives
the crank shaft which further
drives the gear arrangements;
which further drives the another
crank shaft.
This crank shaft then moves the
magnet in “to and fro” motion into
a coil.
10. COMPONENTS
1. MS plate
The Mild steel plate is a square plate of size 1feet*1 feet
i.e. 300 mm*300 mm.
The thickness of the plate is 3mm.
We are using two plates here one base plate and one upper
plate to place foot.
11. 2. Pipes
There two types of cylindrical Mild Steel pipes are used.
One is for bottom plate of diameter 30 mm and
thickness of 3 mm which contains spring placed into it,
while other pipe is welded to upper plate of diameter 20
mm, and of thickness 3 mm.
The length of both the pipes is 100 mm.

17. ADVANTAGES
Power generation is simply walking on
the step
Power also generated by running or
exercising on the step.
No need fuel input
This is a Non-conventional system
Battery is used to store the generated
power
18. APPLICATIONS
Applications of the foot step power
generation are,
This can be implemented on railway
station to generate electric power.
In bus station.
In car parking system.
In Airports.
In Lift system.
In car lifting system.
In street lights
Electric escalators
19. FUTURE SCOPE :
We can use this principal in the speed breakers at
high ways , where the vehicles rush too much, thus
increase input torque and ultimate output of
generator.
By increasing the size and multiplying the frequency
of array of system we can build a big power option
for domestic and public use.
If we use this project at very busy stairs , then we
produce efficient useful electrical energy for large
purposes .
The design of the project can be further modified for
commercial and large scale use.
20. CONCLUSION
In concluding the words of our project, since
the power generation using foot step get its
energy requirements from the Non-renewable
source of energy.
There is no need of power from the mains
and there is less pollution in this source of
energy.
It is very useful to the places all roads and as
well as all kind of foot step which is used to
generate the non-conventional energy like
electricity.
It is able to extend this project by using same
arrangement and construct in the
footsteps/speed breaker so that increase the
power production rate by fixing school and
