Harvesting Water Drop Energy by a Sequential Contact‐Electrification and Electrostatic‐Induction Process

Abstract

A new prototype triboelectric nanogenerator with superhydrophobic and self‐cleaning features is invented to harvest water drop energy based on a sequential contact electrification and electrostatic induction process. Because of the easy‐fabrication, cost‐effectiveness, and robust properties, the developed triboelectric nanogenerator expands the potential applications to harvesting energy from household wastewater and raindrops.
