Below with reference to Fig. 4 a to Fig. 7 b, the concrete structure of the triboelectricity machine in the utility model is described in detail:
Fig. 4 a and Fig. 4 b show respectively perspective view and the cross-sectional view of the first structure of triboelectricity machine.This triboelectricity machine comprises: the first electrode 101, the first high molecular polymer isolation layers 102 that are cascading, and the second electrode 103.Particularly, the first electrode 101 is arranged on the first side surface of the first high molecular polymer isolation layer 102; And the second side surface of the first high molecular polymer isolation layer 102 and the second electrode 103 are oppositely arranged.In said structure, relative fixing between the first side surface of the first high molecular polymer isolation layer 102 and the first electrode, contact friction induce electric charge at the second electrode and the first electrode place when being squeezed between the second side surface of the first high molecular polymer isolation layer 102 and the second electrode.Therefore, in the present embodiment, two faces that the first high molecular polymer isolation layer and the second electrode are oppositely arranged are as the frictional interface of triboelectricity machine, and the first above-mentioned electrode and the second electrode are respectively as two output terminals of triboelectricity machine.
