3. Introduction
 Walking is the most widespread kind of human activity. When a person walks, he loses energy to the
road surface in the form of impact, vibration, sound, and so on, as a result of his weight being transferred
to the road surface through foot falls on the ground.
 This energy can be harnessed and turned into a form that can be used, such as electricity. If installed in
the pathway, this gadget can transform foot impact energy into electrical energy.
 Ninety-five percent of the pedal power exerted is turned into energy. Pedal power is a simple,
inexpensive, and convenient source of energy that may be used for a variety of tasks.
 The proposal for utilizing waste energy from human movement to generate electricity is particularly
relevant and significant for densely populated countries such as India and China, where the mobility of
their people will prove to be a godsend in generating electricity from their footsteps.
 Roads, railway stations, and bus stops are all overcrowded in India, and millions of people travel around
the clock. As a result, this promising technology can be used to generate a vast amount of power.

4. Literature Survey
 Dailey & Sandra- Ninety-five percent of the pedal power exerted is turned into energy.
Pedal power is a simple, inexpensive, and convenient source of energy that may be used for
a variety of tasks. Human kinetic energy, on the other hand, can be used in a variety of
ways, including generating electricity using various methodologies, and several
organization's are already using human-powered technologies to create electricity to power
small electronic items.[4]
 S.S.Taliyan, B.B. Biswas,R.K. Patil and G. P. Srivastava : The piezoelectric material
converts the pressure applied to it into electrical energy. The source of pressure can be
either from the weight of the moving vehicles or from the weight of the people walking
over it.[7]

5. Literature Survey (continued)
 Li, Zheng; Mao, Shaohua; Zhu, Shi - Piezoelectric sensors have proven to be versatile tools
for the measurement of various processes. They are used for quality assurance, process
control and for research and development in many different industries it was only in the
1950s that the piezoelectric effect started to be used for industrial sensing
applications.Since then, this measuring principle has been increasingly used and can be
regarded as a mature technology with an outstanding inherent reliability.[1]

6. Research Gap
 Before our research the connections are done for either
parallel or series connection It can be seen from the
recent research that the voltage from a series connection is
good but the current obtained is poor, whereas the current
from a parallel connection is good but the voltage is poor.
 Max. Voltage-0.8 volt
 Max. Current- 0.4 mA (D.C.)
 But this problem is rectified in a series- parallel
connection where a good voltage as well as current can
be obtained.
 Max. Voltage- 0.8 volt
 Max. Current- 2 mA (D.C.)

7. Problem Statement
 We daily lose our energy while travelling like on road, stairs but what-if we can store that
energy and use when required.
 We worked on a device that can convert human effort into electrical energy and store this
energy for further use.
 We tried to fabricate the device which utilize the human effort to generate the electricity
and promote the non-conventional energy source.

11. Experimental Results / Analysis
 It is especially suited for implementation in crowded areas. This can be used in street lighting
without use of long power lines. It can also be used as charging ports, lighting of pavement side
buildings. As a fact only 11% of renewable energy contributes to our primary energy . If this
project is deployed then not only we can overcome the energy crises problem but this also
contributes to create a healthy global environmental change.
 For 10kg of mass we get 0.01 watt power.
 For 60kg of mass we get 0.73 watt power.
 Durable and have the life approximately of 5 year.
BIT 11

12. Conclusion
 In the method both mechanical and electrical part places major role. Thus the method is quite
easy to implement and maintain. Thus to make the whole system for urban area application more
design parameters should consider. Now-a days numbers of energy sources are present, non-
renewable and renewable, but we still cannot exceed our energy needs . Among these, the human
population is one of the resources. Energy can be generated by walking down the stairs. The
energy generated will be stored and then we can use it for domestic purpose. This system can be
installed in installed in homes, schools, universities, where people move around the clock.

13. Future Scope
 Utilization of wasted energy is very much relevant and important for highly populated
countries in future.
 Researcher already started experimenting the use of piezoelectric effect for energy
generation.
 In future, we will be able to implement it on the walking tiles .
 There is a great scope of non-conventional sources and renewable source and this one is
that source.
 In future, we are going to apply this concept on the Gym equipment and speed breakers.
 We will be enhancing the strength of our product so that it can sustain a mass of more than
60kg.
