Lin, Z.-H., Cheng, G., Lee, S., Pradel, K. We show that spreading of an impinged water droplet on the device bridges the originally disconnected components into a closed-loop electrical system, transforming the conventional interfacial effect into a bulk effect, and so enhancing the instantaneous power density by several orders of magnitude over equivalent devices that are limited by interfacial effects.
#Electric generator plus#
Here we develop a device to harvest energy from impinging water droplets by using an architecture that comprises a polytetrafluoroethylene film on an indium tin oxide substrate plus an aluminium electrode. An alternative, the water-droplet/solid-based triboelectric nanogenerator, has so far generated peak power densities of less than one watt per square metre, owing to the limitations imposed by interfacial effects-as seen in characterizations of the charge generation and transfer that occur at solid–liquid 1, 2, 3, 4 or liquid–liquid 5, 18 interfaces. Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low water supply. However, achieving a high density of electrical power generation is challenging. Extensive efforts have been made to harvest energy from water in the form of raindrops 1, 2, 3, 4, 5, 6, river and ocean waves 7, 8, tides 9 and others 10, 11, 12, 13, 14, 15, 16, 17.
