Walk to Watt: Energy harvesting smart park using piezoelectric technology

The modern world faces increasing energy demands and a growing push toward sustainability. Piezoelectric energy harvesting provides an innovative method for generating electricity by converting mechanical stress such as footsteps into electrical power. The concept of “Walk to Watt” envisions a smart park that integrates piezoelectric floor tiles to collect kinetic energy from human movements and convert it into usable electrical energy for powering park infrastructure like lights, sensors, and IoT systems. We can support decentralized power generation, lessen reliance on traditional grids, and advance green technologies in public areas by utilizing this abundant energy source. The use of piezoelectric materials has drawn a lot of attention among emerging energy harvesting technologies because of their capacity to directly transform mechanical stress into electrical energy using comparatively simple systems. Piezoelectric devices are perfect for integration into flooring systems, sidewalks, train stations, and other pedestrian-heavy areas because they are small, robust, and effective for small-scale energy generation. The design and implementation of a footstep energy harvesting system with piezoelectric sensors is the main goal of this study. The mechanical stress caused by footsteps can be recorded and transformed into useful electrical energy by placing these sensors beneath walkways and other pedestrian surfaces. In order to contribute to the larger vision of smart cities and sustainable urban infrastructure, the study also discusses system architecture, energy storage methods, possible applications, and future improvements.
