Abstract

The present invention relates to a gear meshing structure direct current rotating friction nano power generation device, comprising a first gear assembly, a second gear assembly and a third gear assembly, the first induction electrode is provided on the teeth of the first gear assembly, and the first gear assembly An induction electrode is provided with a first friction layer, a second friction layer is provided on the teeth of the second gear assembly, a third induction electrode is provided on the teeth of the third gear assembly, and the third induction electrode There is a third friction layer on the outside; the second gear assembly rotates under the drive of the drive mechanism so that the first friction layer and the second friction layer, the second friction layer and the third friction layer produce contact friction, and different charges are in different The surface of the gear assembly gathers, and a potential difference is generated between the first induction electrode of the first gear assembly and the third induction electrode of the third gear assembly, driving electrons to flow in the same direction, thereby outputting a DC signal to the outside. The invention can output direct current without rectification circuit.

Description

technical field [0001] The invention relates to a friction nanometer power generation device, in particular to a gear meshing structure direct current rotation friction nanometer power generation device.
