Liquid–Liquid Triboelectric Nanogenerator
In article number 2208393, Ho Cheung Shum and co‐workers investigate mechanisms of contact electrification in various liquid‐liquid systems and thus demonstrate a liquid‐liquid triboelectric nanogenerator to harvest energy from rainwater. It can generate a high charge density (3.63 μC/L) with high output stability (crest factor ≈1.1), highlighting the promise...
As one of the most widely distributed water resources, rainwater contains tremendous energy that cannot be effectively utilized by the conventional electromagnetic generators. Triboelectric nanogenerators (TENGs) represent a distributed method to convert trivial mechanical energy into electricity based on contact electrification. Benefiting from the large and replenishable contact interfaces in liquid–liquid...
