Mechanistic approach to generate the Electric double layer (EDL) for power supply through (a) peristaltic pump, (b) water reservoir (c) TENG cell showing the EDL = IHP + OHP at the interface of solid–liquid and the reduction of the zeta potential after the IHP to the bulk segment of the flow liquid. (d) Electrometer. (Supporting information showed the picture of live experimental set-up of for the proposed flow TENG Apparatus).
