SINGLE-ELECTRODE FRICTION NANO GENERATOR, POWER GENERATION METHOD AND SELF-DRIVEN TRACKER

摘要

The present invention provides a single-electrode triboelectric nanogenerator based on different triboelectric properties of polymer material and metal material, and further provides a tracking system based on the nanogenerator. The tracking system comprises an array formed by a plurality of nanogenerators; when an object moves on the tracking system, a pressure is applied on the nanogenerator causing two layers of triboelectric material constituting the nanogenerator to contact with each other and thereby outputting an electrica signal. When the object has left the nanogenerator, the two layers of the triboelectric material constituting the nanogenerator are separated from each other under the action of an elastic material and output an electrical signal as well. The tracking system based on the triboelectric nanogenerator according to the invention may track the movement path of certain objects, and has advantages of self-driven, low cost, and simple structure.
