Abstract

This research explores the development of a sustainable piezoelectric harvester to capture energy from water droplets, offering a novel approach to renewable energy and addressing the challenges of harnessing energy from low-power sources, like water droplets. The study aims to design and create a prototype piezoelectric harvester that efficiently captures energy from water droplets and converts it into usable electricity, focusing on the impact of varying droplet sizes. The setup involved testing the harvester with both Small Droplet Sizes (SDS) and Big Droplet Sizes (BDS) to measure energy output. The results indicated a significant difference in energy output between the two droplet sizes. Specifically, larger droplet sizes produced a significantly higher voltage output compared to smaller droplet sizes, demonstrating a direct correlation between droplet size and energy generation. Statistical analysis, employing a t-test, confirmed these differences to be statistically significant (p < 0.05), supporting the alternative hypothesis that droplet size variations impact the energy output of the piezoelectric harvester. The findings contribute to the existing body of knowledge on piezoelectric devices, promoting sustainability and energy conservation. This study provides insights for future researchers and STEM students interested in integrating piezoelectric technology into existing infrastructures.
