Mechanical Energy Harvesting from Footprints for Renewable Energy Applications

The work undertaken focuses on the design, development, and implementation of a footprint-based energy harvesting system, aimed at harnessing renewable energy from everyday human activities This project focuses on designing and implementing a footprintbased energy harvesting system that converts human footsteps into usable electrical energy using piezoelectric plates. These plates, arranged beneath a robust walking platform, deform slightly under pressure, generating electrical charges. The small amounts of AC voltage produced are converted to DC using a bridge rectifier and stored in rechargeable batteries. Voltage regulators, capacitors, and transformers ensure safe and stable storage. A microcontroller monitors key parameters like voltage, current, and energy generation in realtime. The modular design allows scalability, making it suitable for areas like public walkways and institutions. The harvested energy, though small, is enough to power devices like LEDs, mobile chargers, and clocks. This prototype supports green infrastructure and educates on renewable energy. It promotes the use of micro-energy systems and paves the way for smart city applications, standing as a small yet impactful step toward sustainable, decentralized energy system.
