▎ 摘　　要

NOVELTY - The nano-generator has a first friction unit provided with a first electrode layer (1) and a positive friction layer (2). A second friction unit is provided with a negative friction layer (3) and a second electrode layer (4). The first electrode layer is arranged on an upper surface of the positive friction layer. The second electrode layer is arranged on a lower surface of the negative friction layer. A friction layer microstructure (5) is fixed between the positive friction layer and the negative friction layer, where the friction layer micro-structure is nanometer concave-convex micro-structure. The first electrode layer and the second electrode layer lead out wires to output electrical energy. USE - Electro-hydrodynamic jet three-dimensional printing triboelectric nano-generator for printing of molding materials and composites. ADVANTAGE - The nano-generator solves the problems of low conversion efficiency and low output power when manufacturing three-dimensional printing triboelectric nanogenerators. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing an electro-hydrodynamic jet three-dimensional printing triboelectric nano-generator. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an electro-hydrodynamic jet three-dimensional printing triboelectric nano-generator. 1First electrode layer 2Positive friction layer 3Negative friction layer 4Second electrode layer 5Friction layer microstructure
