Perlas (Piezoelectric energy for residential lighting and advance solutions): an arduino uno-based piezoelectric energy harvesting system for residential lighting applications

This study explores the development and testing of a piezoelectric energy-harvesting prototype designed to convert mechanical stress from foot traffic into electrical power for residential lighting applications. With the increasing demand for sustainable energy solutions, piezoelectric sensors present a viable alternative for generating electricity from everyday activities. The prototype consists of piezoelectric sensors integrated into a flooring system, an Arduino Uno for energy tracking, a voltage regulator, and an energy storage component. A series of experiments were conducted to evaluate the system’s efficiency, focusing on the relationship between applied force and voltage output. The results revealed a strong positive correlation (r = 0.92) between mechanical stress and energy generation, indicating that increased force leads to higher voltage output. Additionally, an ANOVA test confirmed a statistically significant difference (p < 0.05) in energy output across varying pressure levels, demonstrating the effectiveness of the system in energy harvesting. The prototype successfully stored harvested energy and powered LED lights, validating its potential for practical applications. However, improvements in energy storage capacity and circuit efficiency are necessary for large-scale implementation. This study highlights the feasibility of integrating piezoelectric energy harvesting into residential settings, contributing to the advancement of sustainable and renewable energy solutions. Future research should explore optimization techniques, larger-scale applications, and economic feasibility assessments to enhance its viability for broader use.
