An electrical energy transmission and reception system based on triboelectric nanogenerators

Abstract

The present invention provides a system for transmitting and receiving electric energy based on a triboelectric nanogenerator, which includes a driving component, a first triboelectric nanogenerator and a second triboelectric nanogenerator driven by the driving component, and connected to the first triboelectric nanogenerator and the second triboelectric nanogenerator. A circuit management module between the nanogenerators, and a capacitor connected between the second triboelectric nanogenerator and the load, and the capacitance of the capacitor is equivalent to the equivalent capacitance of the second triboelectric nanogenerator; the first triboelectric nanogenerator adopts The independent friction layer type triboelectric nanogenerator is driven by the driving component to generate alternating current, and the circuit management module rectifies the alternating current generated by the first triboelectric nanogenerator and converts it into a direct current current, which is sent to the second triboelectric nanogenerator and capacitor; The second triboelectric nanogenerator adopts a contact-slip type triboelectric nanogenerator. During the driving process of the driving component, the electric charge flows back and forth between the second triboelectric nanogenerator and the capacitor to form electrical energy output to the load.

Description

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 power electronic components; second, the contact-separated charge pump needs a higher power to generate effective and large enough electric power driving frequency, which limits its range of application in low-frequency environments; third, the contact-separation charge pump requires a large installation space due to the necessary travel distance for ensuring material contact and separation, which also limits its scope of use
