Liquid-solid contact triboelectrification and its use in self-powered nanosensor for detecting organics in water

A fully packaged liquid-solid triboelectric TENS were fabricated basing on the friction between polytetrafluoroethylene filtration membranes and water. Compared with solid-solid triboelectrication based TENS, the liquid-solid TENS can has higher selectivity and sensitivity for detecting dopamine with the detection limit of 0.1 µM and a linear range from 10 µM to 1 mM.276
