Power Generation Using Human Foot Steps

This research paper presents the design, fabrication, and optimization of a footstep power generation system capable of converting human kinetic energy into usable electricity. The system employs a rack and pinion mechanism to transform the linear motion of footsteps into rotary motion. Spur gears are integrated to amplify rotational speed and torque, thereby enhancing energy conversion efficiency. The mechanical energy generated is converted into electrical energy using low-RPM dynamo, which is then stabilized and stored in a battery for off-grid applications. This innovative approach combines traditional mechanical components with modern energy harvesting techniques, offering a durable and cost-effective alternative to piezoelectric systems. Performance metrics, including voltage output, energy storage capacity, and gear ratio efficiency, are evaluated through rigorous testing. The system generates 3V per footstep, effectively powering four 1.5V LED lights. Designed for scalability, this system demonstrates potential for deployment in high-traffic areas such as schools, transit hubs, and malls, effectively harnessing wasted kinetic energy. By addressing challenges such as material durability, energy loss, and precise gear alignment, the paper highlights the viability of mechanical energy harvesting as a practical and sustainable renewable energy solution.
