Based on the physical properties of the electric dipole and the electric coupling layer,the friction layer or the electrode layer of the triboelectric nanogenerators is regarded as a electric coupling layer,respectively. An additional polarization current is generated to establish the electric potential difference between the electrode layers. The equivalent electric dipole moment of the electrode layer is always equal to the negative value of the incremental electric dipole moment of the friction layer,so the conservation of the electric dipole moment is proposed of the system of the friction layer and the electrode layer. The mathematical expression and calculation process of the electric coupling layer model of the triboelectric nanogenerators were given. The basic models of vertical contact separated,horizontal sliding and independent layer triboelectric nanogenerators were studied,the short-circuit transfer charge,open-circuit voltage,additional polarization current density and inherent capacitance were calculated by using the electric coupling layer model. The results show that the model is simple and efficient,and the analytical solution of most parameters can be obtained. The conclusion are highly consistent with the existing ones.
