FABRICATION OF A TRIBOELECTRIC ENERGY CELL EMPLOYING VARIOUS SOURCES OF WATER

---

Research and development efforts are being carried out to harvest energy from water in the forms of rain, river tides, and ocean waves. Traditional power generation systems are inefficient and cost-consuming to achieve a high density of electrical energy. As an alternative, utilizing the triboelectric energy generation principle, a device comprising of three components: the upper electrode layer, polymer film (insulating layer), and the lower electrode layer is fabricated to harvest energy from impinging water droplets by using an architecture that comprises a polymer film (insulating layer) on a lower electrode layer plus an upper electrode layer. The impinged water droplet bridges the disconnected components into a closed-circuit electrical system on spreading. The water-droplet-based energy cell works following the principle of contact electrification and electrostatic induction between water droplets and polymer film (insulating layer).
