INTRODUCTION

The world is running on electricity

The need of power is increasing day by day.

Non-conventional energy is very essential atthis time to our nation.

Walking is the most common activity in day to

day life. This energy can be tapped and converted in the

usable form such as in electrical form.

FOOTSTEP ELECTRIC

CONVERTER DEVICE (FSEC) This device, if embedded in the footpath, can

convert foot impact energy into electrical form.

The downward movement of the plate results inrotation of the shaft of an electrical alternator,fitted in the device, to produce electrical energy

The generated energy can be stored in a lead acid

battery.

The electricity generated from these devices can beused for street lights.

Energy storage

The power generated by the foot step generator can be storedin an energy storing device.

The output of the generator was fed to a 12 V lead acid battery,

through an ac-dc converter bridge.

Initially, the battery was completely discharged. Then, theFSEC was operated by applying foot load and energy wasstored in the battery.

Commonly used is lead acid battery.

Fig. 6.: Multi Unit FSEC Platform

The platform in Fig.6 is provided castor wheels,

and can be placed at any public place where there is

continuous movement of people.

This unit is designed for persons weighing 50 Kg

and above.

The unit is fitted with two 12 V, 26 Amp lead acid

batteries for storing the output energy from this unit.

Also, an inverter is provided to convert 12 V DC

from battery to 230 V AC supply for general use.

Experiment


11/25

When a person walks over to the platform, the reading on the

energy meter was observed to be incremented by 3-5 J per step,

depending on the weight of the person.

As millions of people are on the move in cities, significant amount

of electricity can be generated by installing these devices at places

where the public walk through.

FOOTSTEP ELECTRICITYGENERATION USING PAVEGEN

Paving slabs that convert energy from people's footsteps into electricity

The recycled rubber "Pavement" paving slabs harvest kinetic energy from the impact of

people stepping on them and instantly deliver tiny bursts of electricity to nearby appliances.

The slabs can also store energy for up to three days in an on battery, according to itscreator.

HARVESTERS.

This works as follows: droplets of liquidare placed between electrodes coated indielectric film.

Both droplets and electrodes areconnected to an external electricalcircuit.

A tube of a millimeter wide and fourmillimeters long would contain theelectrodes and droplets. In total thedevice would take up 40cm2 which can

be incorporated in the sole of the shoe. Each foot would generate up to 10W,

which is enough to charge a phone or alaptop.

Advantages Reliable, Economical, Eco-friendly

Compact

Highly sensitive

No moving parts long service life

Disadvantages Output is very small

Number of crystals should be high to get

sufficient output. The crystals have to be replaced after 5

years

CONCLUSION

This paper presents an adaptive approach to harvesting electrical energy

from footsteps.

Different methodologies for generation of electricity by walking is

reviewed and analyzed.

Very much relevant and important for highly populated countries like

India and China.
