Are Triboelectric Nanogenerators More Efficient Than Piezoelectric Transducers in Generating Energy from Precipitation?

This review examines two primary methods for harvesting energy from precipitation: triboelectric nanogenerators (TENGs) and piezoelectric transducers, which are leading technologies in converting mechanical energy from rain into electrical energy. The comparison between TENGs and piezoelectric transducers focuses on their operational mechanisms, material characteristics, and environmental factors such as water pH and temperature. The review highlights that TENGs offer greater design flexibility, efficiency in low-intensity rain, and cost-effectiveness, while piezoelectric transducers excel in high-frequency environments. The development of hybrid systems combining both technologies presents a more efficient and sustainable solution for rain energy harvesting.
