The working principle is as follows: when in use, the first aluminum electrode layer and the second aluminum electrode layer of the friction nano generator unit 4 are respectively and electrically connected with the conductive slip ring 6 through wires; when the wind blows (downwind), the fan blades 12 on the friction nanometer generator unit 4 are blown and opened at a certain angle to drive the insulating turbine disc 3 to rotate; next, the insulating turbine disk 3 is rotated to a position where the other fan blade 12 is opened, and the fan blade is restored to its original state by the influence of wind resistance. Thus, three fan blades on the insulating turbine disc 3 are lifted by wind in sequence, and the insulating turbine disc rotates clockwise by taking the steel pipe as a shaft; in an initial state, when the first friction dielectric film (FEP film) on the fan blade 12 is in contact with the second friction dielectric film (PP film) on the base, the FEP film has a negative charge, and the PP film has the same number of positive charges. When the fan blades are lifted by the wind for a period of time, the FEP film is more electronegative than the PP film due to the contact electrification, and thus the FEP film tends to acquire electrons to remain equal to the positive charge on the first aluminum electrode layer. At this time, charges are transferred from the first aluminum electrode layer to the second aluminum electrode layer through an external circuit to maintain the balance of the electrostatic voltage. When the fan blade is completely lifted, the positive and negative charges of the first aluminum electrode layer and the second aluminum electrode layer are equal, and no charge transfer exists in an external circuit. When the fan blades rotate to the upwind, the fan blades 12 will quickly descend. At this time, the second aluminum electrode layer will pick up more electrons. To keep the electrostatic potential balanced, electrons will be transferred to the first aluminum electrode by an external circuit. Since the lifting process of the fan blade is periodic, the charge transfer caused by the first aluminum electrode layer and the second aluminum electrode layer is also periodic, and therefore the electric signal is an alternating current output.
The embodiment accurately measures the output performance of the TD-TENG device under the ideal trigger condition generated by the linear motor. The short circuit current, open circuit voltage and transferred charge of the TD-TENG device and the charging voltage of the different capacitors were measured using a pre-current amplifier (Keithley6514 system electrometer). The data display and storage is accomplished by installing LabVI EW software on the computer.
And (3) testing results: when the effective contact area of the fan blade 12 is 44cm2The device can generate transfer charges as high as 50nC, the open-circuit voltage is 150V, and the short-circuit current is 7 muA; when the effective contact area of the fan blade 12 is 83cm2When the voltage is high, 82nC of transferred charges can be generated, the open-circuit voltage is 230V, and the short-circuit current isThe peak power is 9 muA, and when the external load resistance is 7M omega, the maximum peak power reaches 0.37mW, so that 180 series-connected light-emitting diodes can be directly lightened; as the contact area of the fan blades 12 increases, not only the wind resistance of the fan blades 12 increases, but also the wind speed to be raised increases. When the ambient wind speed is very low, the friction nanometer generator units on the upper layer of insulating turbine disc can normally operate, and when the ambient wind speed is very high, the friction nanometer generator units on the upper layer of insulating turbine disc and the lower layer of insulating turbine disc can simultaneously and orderly operate.
