Extensive efforts have been made to harvest energy f from water in the form of raindrops, river and ocean wave, tidal and others. However, achieving a high-density of electrical power generation is challenging. Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with water supply. Alternative, the water droplet or solid-based electric nano-generator, has so far generated peak power densities for less than one watt per square meter, owing to the limit at ions imposed by interfacial effects as seen in characterization of the charge generation and transfer that occur at solid-liquid or liquid-solid interfaces. Here we develop a device to harvest energy from impinging water droplet s by using an architecture that compromises a polytetrafluoroethylene film on an indium oxide substrate plus an aluminium electrode. We show that spreading of an impinged water droplet on the device bridges, the originally disconnect ed component s into a closed-loop electrical system, transforming the conventional interfacial effect into bulk effect, and so enhancing device that is limited by interfacial effects.
