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. KEY POINTS: The main purpose of foot step power generation is to provide more power by using piezo . A piezo film is capable of generating 40V. To store this generated power we require a 12 v rechargeable battery which will be connected to the inverter. This inverter will convert the 12v DC to the 230v AC.

5. 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

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

8. APPLICATION: Footstep power generation can be used in emergency power failure situations lt can be used for Agricultural, Home applications, Street lighting and etc... Metros and Rural applications

9. Advantages & Disadvantages: 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 Initial cost is too high Implementation is difficult Less maintenance, but difficult

10. 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
