Action note: In: Summary: ABSTRACT: In recent years, the growing demand for clean and sustainable energy sources has led to the exploration of innovative technologies for harvesting en ergy from various sources. One promising avenue is the development of footstep power generators, which harness mechanical energy from human footsteps to generate electricity through the use of piezoelectric sensors. However, the effective implementation of this technology is still a challenge due to several unresolved issues and limitations. This study aims to optimize these generator's efficiency by comparing the voltage output from three configurations of nine piezoelectric transducers: center-assembled, circular, and square formations. Tests showed that the circular configuration produced the highest average voltage (0.06 V) and power (1.265 mW), compared to the square (0.05 V, 1.053 mW) and center-focused (0.0398 V, 0.6115 mW) configurations. T-tests confirmed significant performance differences between the configuations. The findings suggest that circular placement of transducers is the most efficient for footstep power generators, highlighting its potential to enhance the performance and efficiency of renewable energu solutions. This configuration can maximize energy capture from human movement, making it a promising approach for sustainable energy technologies. Other editions:
