3. introduction We are generating electrical power non-conventional method by simply walking or running on the foot step Non conventional energy using foot step is converting mechanical energy in to the electrical energy The basic principle behind this system is piezoelectric effect

4. Piezoelectric material certain materials have the ability to build up an electrical charge from having pressure and strain applied to them. Piezoelectricity refers to the ability of some materials to generate an electric potential in response to applied pressure such materials are called piezoelectric material Eg : Quartz  Belemnite  Gallium orthophosphate Tourmaline

5. Piezoelectric effect Piezoelectric Effect  is the ability of certain materials to generate an electric charge in response to applied mechanical stress.

6. working 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. The output of the piezoelectric material is not a steady one. So a bridge circuit is used to convert this variable voltage into a linear one. Again an AC ripple filter is used to filter out any further fluctuations in the output. The output dc voltage is then stored in a rechargeable battery. The inverter is converts the DC into AC

7. . A force is applied along a neutral axis of the piezoelectric crystal and the charges are generated along the perpendicular to the line of force The amount of charge depends up on the * Geometrical dimensions of the respective piezoelectric element * The pressure applied

10. BATTERY Lead- Acid Battery High quality and reliability Long life Maintenance free

11. Inverter Inverter is an electric device that coverts direct current DC in 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

12. Advantages Non conventional method, renewable energy source Eco friendly Reliable Self generating – no external power required Less maintenance cost Ultra low noise An alternative way of power generation

13. disadvantages Initial cost is too high Implementation is difficult Less maintenance , but difficult

14. application Footstep power generation can be used in emergency power failure situations It can be used for Agricultural ,Home applications , Street lighting and etc… Metros and Rural applications

15. Conclusion Footstep power generation system is economical, affordable energy solution to common people It can be used for many application in rural areas where power availability is less or totally absence
