For versatile mechanical energy harvesting from arbitrary moving objects such as humans, a new mode of triboelectric nanogenerator is developed based on the sliding of a freestanding triboelectric‐layer between two stationary electrodes on the same plane. With two electrodes alternatively approached by the tribo‐charges on the sliding layer, electricity is effectively generated due to electrostatic induction. A unique feature of this nanogenerator is that it can operate in non‐contact sliding mode, which greatly increases the lifetime and the efficiency of such devices.
