The increasing demand for electricity has driven the development of environmentally friendly and sustainable alternative energy sources. Piezoelectric technology offers an innovative solution by converting mechanical energy, such as human foot pressure, into electrical energy. However, most previous studies have focused only on individual material testing, not the integration of a functional floor system with optimal circuit configuration. This study aims to design and test a small-scale piezoelectric floor prototype capable of harvesting energy from pedestrian activity. The prototype utilizes PZT ceramic sensors (27 mm) and was tested using parallel and series circuit configurations. The results show that the prototype can generate an actual voltage of 83.65 V (parallel) and 174.7 V (series) from a total of 5000 footsteps over five months. Although the actual voltage is lower than the ideal due to energy losses and pressure inconsistencies, the system remains functional for low-power applications such as LED lighting or IoT sensors. These findings demonstrate the potential of implementing piezoelectric floor systems in public areas as an efficient, eco-friendly, small-scale renewable energy solution that supports smart building concepts.
