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.

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.

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.

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

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.

Liquid crystal display (LCD):Liquid crystal display (LCD):
A liquid crystal display (LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures.
Its uses include monitors for computers, televisions, instrument panels, and other devices ranging from aircraft cockpit displays, to every-day consumer devices such as gaming devices, clocks, watches, calculators, and telephones.

WorkingAnd 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. HWhen ever force is applied on piezo electric crystals that force is
converted to Electrical energy is used to drive DC loads. ere we are using AT89S52 to display the amount of battery get
charged whenever we place our foot on piezo electric transducer.

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.
