Energy Harvesting from Human Body Motion - Stepping-on System

There is an increasing need for step-on energy harvesting systems that can transform human foot pressure into electrical power to energize low-power devices, for example, lights or small fans. In the current work, a harvesting system that converts kinetic energy produced during stepping into electrical energy through a pendulum-to-rotary power conversion mechanism is presented. In order to achieve effective energy transmission, the system is designed using a pendulumpulley architecture that is adjusted for foot pressure dynamics. The mechanism produces energy output while guaranteeing user comfort and versatility in a range of applications by meticulously regulating the pendulum's length, mass, and pulley ratios. Power and motion calculations are presented and the developed design is discussed in different parameter cases. The results show the effectiveness of this application in power production. With possible uses in both public and private areas that might profit from self-sufficient, motion-activated ventilation systems, this solution exemplifies a realistic, environmentally friendly method of energy harvesting.
