▎ 摘　　要

NOVELTY - The nano-generator has a first friction unit comprising a first electrode layer (1) and a positive friction layer (2), where the first electrode layer is tightly attached to an upper end surface of the positive friction layer. A second friction layer comprises a negative friction layer (3). A second electrode layer (4) is tightly attached to a lower end surface of the negative friction layer. The first electrode layer and the second electrode layer are connected with a lead. USE - 3D printing composite polymer-based friction nano-generator. ADVANTAGE - The composite polymer-based friction nano-generator solves problem that the friction layer material selection is single, and friction layer structure is limited. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a three-dimensional (3D) printing composite polymer-based friction nano-generator manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a 3D printing composite polymer-based friction nano-generator. 1First electrode layer 2Positive friction layer 3Negative friction layer 4Second electrode layer
