The core technology of triboelectric nanopower generation is mainly composed of two parts, one is the friction part that relies on the friction of two materials with greatly different electronegativity to generate electric energy; the other is the current process of rectifying alternating current into direct current and storing electric energy.

Fig. 8 is the working flow chart of the triboelectric nano-power generation device of the present invention, the principle of generating electric energy by the friction part: when the electrodes are in contact, two layers of thin films with a large difference in electronegativity are rubbed, and when separated, carry opposite charges respectively, forming a potential difference; The upper and lower surface electrodes of the two materials are connected by a load, and the potential difference will cause electrons to flow between the two electrodes to balance the electrostatic potential difference between the films. Once the two contact surfaces coincide again, the potential difference created by the triboelectric charge disappears, allowing the electrons to flow in the opposite direction. In this continuous contact and separation, the output end of the triboelectric generator will output alternating current pulse signals, thereby outputting electrical energy to the outside world.

The working principle of the rectifier and voltage regulator part: convert the alternating current delivered by the friction part into direct current that can be used. A common simple design is a rectifier circuit. The most typical rectifier circuit is a bridge rectifier circuit, which uses the unidirectionality of the diode to change the current into one direction.
