This document describes a footstep power generation system that converts the mechanical energy from walking or running into electrical energy using piezoelectric sensors. The electrical energy is stored in a lead acid battery and can be used to power AC and DC loads. An inverter converts the DC battery voltage to AC voltage. The system provides a low-cost renewable energy solution that could power rural applications and emergency situations by harvesting wasted human biomechanical energy.

4. Introduction
• In this project we are generating electrical
power as non-conventional method by simply
walking or running on the foot step. Non-
conventional energy system is very
essential at this time to our nation.
• Nonconventional energy using foot step is
converting mechanical energy into the
electrical energy.

5. • Man has need and used energy at an increasing rate for
his sustenance and well-being ever since he came
on the earth a few million years ago.
• Due to this a lot of energy resources have been
exhausted and wasted.
• Proposal for the utilization of waste energy of foot
power with human locomotion is very much relevant
and important for highly populated countries like India
and China where the roads, railway stations, bus stands,
temples, etc. are all over crowded and millions of
people move around the clock.

6. • This whole human/ bio-energy being wasted if it can
be made possible for utilization it will be great
invention and crowd energy farms will be very useful
energy sources in crowded countries
• This project uses piezoelectric sensor.
• In this project the conversion of the force energy in
to electrical energy.
• The control mechanism carries the piezo electric
sensor, A.C ripples neutralizer, unidirectional current
controller and 12V, 1.3Amp lead acid dc
rechargeable battery and an inverter is used to drive
AC/DC loads.

7. piezoelectric sensor
A piezoelectric sensor is a device that
uses the piezoelectric effect to
measure pressure, acceleration, strain o
r force by converting them to
an electricalsignal.

8. Inverter
An inverter is an electrical
device that converts direct
current (DC) to alternating
current (AC); the converted
AC can be at any required
voltage and frequency with
the use of appropriate
transformers, switching, and
control circuits.

10. Lead Acid Battery
• Specifications
12V 1.3Ah sealed lead acid battery
1. CE and RoHs
2. high quality and reliability
3. maintenance free
4. long life cycle
• 12V 1.3Ah sealed lead acid battery
General Features:
• Sealed and maintenance free operation.
• ABS containers and covers(UL94HB, UL94-0)optional.
• Safety valve installation for explosion proof.
• High quality and high reliability.
• Exceptional deep discharge recovery performance.
• Low self discharge characteristic.
• Flexibility design for multiple install positions.

11. Working
• When ever force is applied on piezo electric
crystals that force is converted to Electrical
energy is used to drive DC loads. And that minute
voltage Which is stored in the Lead Acid battery.
The battery is connected to the inverter.
• This inverter is used to convert the 12 Volt D.C to
the 230 Volt A.C. This 230 Volt A.C voltage is used
to activate the loads.
• We are using conventional battery charging unit
also for giving supply to the circuitry.

12. Advantages
• Reliable, Economical, Eco-Friendly.
• Less consumption of Non- renewable
energies.
• Excellent linearity over their dynamic range
• Wide frequency range, high frequencies can be measured
• Compact yet highly sensitive
• No moving parts - long service life
• Self-generating - no external power required
• Great variety of models available for nearly any purpose
• Integration of the output signal provides velocity and displacement

13. Applications
• Foot step generated power can be used for
agricultural, home applications, street-
lighting.
• Foot step power generation can be used in
emergency power failure situations.
• Metros, Rural Applications etc.,

14. CONCLUSION
• The project “FOOT STEP POWER GENERATION FOR
RURAL ENERGY APPLICATION TO RUN A.C. AND D.C.
LOADS” is successfully tested and implemented which
is the best economical, affordable energy solution to
common people.
• This can be used for many applications in rural areas
where power availability is less or totally absence.
• As India is a developing country where energy
management is a big challenge for huge population. By
using this project we can drive both A.C. as well as D.C
loads according to the force we applied on the piezo
electric sensor.
