Electric energy transmitting and receiving system based on friction nano-generators

Abstract

The invention provides an electric energy transmitting and receiving system based on friction nano-generators, which comprises a driving assembly, a first friction nano-generator and a second friction nano-generator driven by the driving assembly, a circuit management module connected between the first friction nano-generator and the second friction nano-generator, and a capacitor which is connected between the second friction nanometer generator and the load, wherein the capacitance of the capacitor is equivalent to the equivalent capacitance of the second friction nanometer generator; the first friction nanometer generator adopts an independent friction layer type friction nanometer generator and is driven by the driving assembly to generate alternating current, and the circuit management module rectifies the alternating current generated by the first friction nanometer generator, converts the alternating current into direct current and transmits the direct current to the second friction nanometer generator and the capacitor; and the second friction nanometer generator is a contact sliding type friction nanometer generator, and in the driving process of the driving part, charges flow back and forth between the second friction nanometer generator and the capacitor to form electric energy output to the load.

However, these types of charge pumps are all contact-separated charge pumps. Although the charge density has been gradually increased, they all have inherent shortcomings and deficiencies: First, the voltage and current generated by the contact-separated charge pump are based on There are sharp peaks in the form of pulse waves, which bring great difficulties to the smooth processing of voltage and current that subsequently p
