Integration of Piezoelectric and Light-Dependent Resistor Sensors for Efficient Generation and Utilization of Electricity for Pathways

The ever-increasing demand for energy in our modern world necessitates exploration of innovative and sustainable solutions. However, the research in the integration of piezoelectric materials has highlighted limitations with respect to scalability. This research investigates the potential of piezoelectric materials for harvesting energy from everyday human movement. We look into cost-effective system utilizing piezoelectric sensors embedded under flooring to capture the energy generated by footsteps. This harvested energy can be stored in and boosted for powering devices. This research explores the utilization of piezoelectric energy harvesting technology to create electricity-generating pathways, offering a sustainable solution for powering pathway lights in urban environments. Piezoelectric sensors strategically placed along the pathway surface capture kinetic energy from pedestrian movement, converting it into electrical energy. This energy is stored in rechargeable batteries and undergoes voltage conversion to power pathway lights effectively. A light-dependent resistor (LDR) sensor ensures lights only activate when necessary, optimizing energy usage. An Arduino Uno microcontroller orchestrates light operation based on ambient light conditions. The methodology focuses on efficient energy utilization and provides a practical solution for sustainable pathway lighting. Several prototypes and studies are discussed, highlighting the potential and limitations of piezoelectric energy harvesting technology. The results demonstrate consistent power generation, high energy conversion efficiency, and cost-effectiveness, underscoring the feasibility and effectiveness of the proposed approach.
