3. ABSTRACT Man has needed and used energy at an increasing rate for the substance and well -being since time immemorial. 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 where the railway stations, temples, etc., are overcrowded all round the clock.

4. OBJECTIVE In this project we are converting Mechanical energy into Electrical energy. We are trying to utilize the wasted energy in a useful way. By using Rack and Pinion arrangement we are converting to and from motion of the steps into rotational motion of the dynamo.

5. INTRODUCTION In this topic we are generating electrical power as non-conventional method by simply walking on footstep. Walking is the most common activity in human life. When a person walks, he loses energy to the road. This energy can be tapped and converted in the usable form such as in electrical form.

6. NEED OF THE SYSTEM The utilization of waste energy of foot power with human motion is very important for highly populated countries. India and China where the roads, railway stations, temples, etc. are all over crowded and millions of people move around the clock.

8. CIRCUIT EXPLANATION Step 1: Connect the piezoelectric sensor to the bridge rectifier using wires. The positive and negative terminals of the sensor should be connected to the input terminals of the bridge rectifier. Step 2: Connect the output terminals of the bridge rectifier to a capacitor using wires. The positive and negative terminals of the capacitor should be connected to the positive and negative terminals of the bridge rectifier, respectively. Step 3: Connect a resistor in parallel with the capacitor using wires. The resistor should have a resistance value between 100 kΩ and 1 MΩ. Step 4: Connect an LED in parallel with the resistor using wires. The anode of the LED should be connected to the positive terminal of the capacitor, and the cathode of the LED should be connected to the negative terminal of the resistor.

9. Step 5: Place the piezoelectric sensor on a surface where it can be stepped on. When someone steps on the sensor, it will generate a mechanical deformation, which will be converted into electrical energy by the piezoelectric effect. Step 6: The electrical energy generated by the piezoelectric sensor will be rectified by the bridge rectifier and stored in the capacitor. The resistor will limit the charging current of the capacitor, and the LED will indicate the presence of electrical energy. Step 7: When the capacitor is fully charged, the LED will light up, indicating that there is electrical energy stored in the capacitor. The LED will remain lit until the capacitor discharges completely.

11. When ever force is applied on piezo electric crystals that force is converted to Electrical energy is used to drive DC loads. And 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.

12. APPLICATIONS Foot step generated power can be used for agricultural, home applications, street-lighting. Foot step power generation can be used in emergency power failure situations. Metros, Rural Applications etc.

13. ADVANTAGES Power generation is simply walking on step. No need fuel input. This is a Non-conventional system. No moving parts - long service life. Self-generating - no external power required. Compact yet highly sensitive

14. CONCLUSION In conclusion, footstep power generation using piezoelectric sensors is a promising technology for harvesting energy from human foot traffic. Piezoelectric sensors can generate electricity by converting the mechanical energy produced by footsteps into electrical energy. This technology has the potential to be used in various applications, such as powering low-power electronic devices in public places, remote areas, or even in wearable devices.
