<p>According to the present invention, a unipolar friction power generator is constructed by using different triboelectric properties of a polymer material and a metal material, and a tracking system based on the power generator is manufactured. In the tracking system, an array matrix is formed by multiple power generator units. When an object moves on the tracking system, pressure acts on the power generator, causing two layers of triboelectric materials forming the power generator to contact, to output an electrical signal externally. When the object leaves the power generator, the two layers of triboelectric materials forming the power generator are separated under the action of an elastic material, and also output an electrical signal externally. The tracking system based on the friction power generator in the present invention can track moving paths of some objects, and has the features of a low cost, being self-driven, a simple structure, and the like.</p> |
