WALK THROUGH ENERGY GENERATION

WALK THROUGH ENERGY GENERATION

11INTRODUCTIONThe use of electricity is increasing day by day and non-renewal energy resources is getting exhausted.

The renewal source like solar energy, wind energy etc has various limitation.

In garden electricity can be generated on a large scale as people go for walk.

2PIEZOELECTRIC SIGNALSFirst demonstration of this signal was done by Pierre Currie and Jacques Currie.

There are two types of signals that can be used for technological application are:

The Direct piezoelectric effect.

The Converse effect.3 BLOCK DIAGRAM4Piezoelectric sensor Up converter ckt(Dc to dc converter)BatteryLoad (LED)MicrocontrollerSensor ckt lcd5Piezoelectric sensor Up converter ckt(Dc to dc converter)Battery Load (LED)MicrocontrollerSensor ckt lcdIt is first block which converts applied pressure into electrical energy.6Piezoelectric sensor Up converter ckt(Dc to dc converter)Battery Load (LED)MicrocontrollerSensor ckt lcdBoost the voltage and give to battery charger.7

Approx. 3 times energy than solar and 2 times than wind energy. 19Parameter Solar energy (large)Wind energy Piezo electric(large scale)Efficiency 94.5990.1196.21Average Electricity generated in one hour (in kwph)3.54.58.2Cost

Higher High ModerateCovering required No

No

Yes DisadvantageLarge piezosensors are required.

It requires covering to protect it from rain which makes it costlier.

20 Uniqueness Generation of electricity by using the piezoelectric transducers.

By walking we can generate electricity which is environmental friendly

By this concept we generate electricity on large scale as people goes for walk.

21 Future scopeSolar energy and wind energy can be included in this project.

It can be used in lifts, elevators, staircase etc22 Conclusion Thus by walking in the garden we can generate electricity .

Save fossil fuel for future generation and save our environment23Thankyou 24
