Piezoelectric Electricity Generator Using Footsteps

Abstract: The growing demand for sustainable and decentralized energysources has encouraged the exploration of energy harvesting fromeveryday human activities. This project focuses on the design anddevelopment of a piezoelectric electricity generator that convertsmechanical energy from human footsteps into usable electricalenergy. When pressure is applied to piezoelectric materials embedded beneath a walking surface, they generate an electric charge due to the piezoelectric effect. The produced alternating voltage is conditioned using rectification and energy storage circuits to obtain stable electrical output. The harvested energy can be used to power low-energy devices such as LED lighting,sensors, or charging units in public areas. This system is particularly suitable for high-footfall locations like railway stations, shopping malls, and sidewalks, offering a clean,renewable, and cost- effective supplementary power source. The proposed approach demonstrates the potential of piezoelectric technology in promoting energy efficiency and sustainability through smart infrastructure integration.
