Abstract

The invention provides a self-driven switching type frictional nanometer generator. The generator comprises a friction generating unit and a voltage driven switch, wherein the friction generating unit comprises at least one pair of corresponding frictional layers used for generating opposite triboelectric charges through physical contact and electrodes which are mutually insulated and make contact with the two frictional layers; one electrode of the friction generating unit is connected with the voltage driven switch to serve as an output end of the frictional nanometer generator, and the other electrode of the friction generating unit serves as the other output end of the frictional nanometer generator. Closing and opening of the voltage driven switch are driven by the friction generating unit, electrical output characteristics of the frictional nanometer generator can be regulated and controlled, and the application range of the frictional nanometer generator is extended.
