Piezoelectricity is the phenomenon of electricity generation in response to mechanical strain, and has become an effective means for power generation. The present study focuses on creating a system that generates electrical energy harvesting from human walking. Densely populated areas such as temples, schools, colleges, cinema halls, public roads and other places where people walk around all day are the most suitable places for integrating the setup. Instead of prior studies that primarily focuses on voltage measurement and series connection concentrated construction, this study introduces parallel connection between piezo sensors and deals with both current and voltage. Four piezoelectric sensors are utilized to convert the applied force into electricity. Experimental results demonstrate the feasibility of the proposed system in generating consistent, usable power under typical walking conditions. The module developed in the study can generate maximum output voltage of 3.6 V, a current of 0.0104 mA, and consequently a power of 0.0374 mW in response to a maximum weight of 22.5 kg. This method of energy generation is highly significant to utilize human footsteps without producing any noise, emissions, or environmental pollutants. The findings of the study contribute to the growing field of piezoelectric-based energy harvesting, offering insights into optimizing sensor configurations for scalable applications in sustainable urban infrastructure.
