Efficiency of energy-generating tiles with different types of multipliers

Abstract

Problem. With the urgent need for sustainable and renewable energy solutions, the integration of energy-harvesting technologies in urban infrastructure has become a focal point of innovation. Energy-generating tiles, transforming pedestrian movement into electricity, offer a viable path forward. Yet, their efficiency hinges on the internal design, particularly the type of multipliers used. Goal. This study aims to assess and compare the efficiency of energy-generating tiles equipped with helical and straight-cut gear multipliers, to identify the optimal design for maximizing energy conversion in urban environments. Methodology. An experimental setup was created to test prototypes of the energy-generating tiles under controlled foot traffic conditions. The study measured and analyzed the electrical output and efficiency of tiles with both types of gear multipliers, simulating real pedestrian traffic scenarios. Results. Energy-generating tiles featuring straight-cut gears outperformed those with helical gears in energy output and conversion efficiency. The research also illuminated the influence of pedestrian dynamics, like step force and frequency, on tile performance. Originality. This research advances renewable energy technology by offering a comprehensive analysis of energy-generating tile efficiency with different gear multipliers. It introduces an innovative method for evaluating tile performance, underscoring the significance of gear design in energy conversion. Practical value. The findings have considerable implications for sustainable urban development, suggesting that implementing energy-generating tiles in areas with high foot traffic could significantly enhance urban renewable energy sources. This study not only guides the design of more efficient energy-harvesting tiles but also encourages their broader adoption, supporting urban sustainability goals and the reduction of carbon emissions.
