[0048] The triboelectric power generation device of the first embodiment of the present invention includes a power generating body, a first conductor 3, and a second conductor 4. The power generating body includes a first power generating unit 1 and a second power generating unit 2 capable of elastic deformation. One end of the first conductor 3 is connected to the first power generating unit 1, and the other end is connected to the positive terminal of an external electrical component 5. One end of the second conductor 4 is connected to the second power generating unit 2, and the other end is connected to the negative terminal of the external electrical component 5. When the first power generating unit 1 undergoes elastic deformation, it generates positive charges through internal triboelectric charging.

When this triboelectric power generation device supplies power to the external electrical component 5, since the first power generating unit 1 and the second power generating unit 2 respectively carry positive and negative charges, a potential difference exists between them, which can form a current, thus providing electrical energy to the external electrical component 5.

[0049] The first power generation unit 1 of this application includes a first electrode layer 1-1 and a first film layer 1-2 connected to the first electrode layer 1-1.

This thickness ratio of the first film layer 1-2 to the first insulating substrate 1-3 can achieve the blocking of electron transmission and ensure better elasticity of the first power generation unit. In one embodiment, the first insulating substrate 1-3 is an insulating film, and its material is one or more of common polymers with good plasticity such as polyacrylic acid, polyethylene terephthalate, polymethyl terephthalate, polyvinyl chloride, polyimide, and nylon. When it is made of two or more materials, the first insulating substrate 1-3 is a copolymer of the above two or more materials. Preferably, the thickness of the first insulating substrate 1-3 is 0.05mm-2.5cm. This thickness range can reduce the volume of the first power generation unit 1 while ensuring electrical safety.

[0051] The second power generation unit 2 of this application includes a second electrode layer 2-1 and a second film layer 2-2 connected to the second electrode layer 2-1. The connection between the second electrode layer 2-1 and the second film layer 2-2 can be either a connection only at their edges or a complete connection of both layers. In this application, the second electrode layer 2-1 is connected to the second wire 4; the second film layer 2-2 is a film layer capable of adsorbing positive charges; the second electrode layer 2-1 and the second film layer 2-2 undergo elastic deformation, generating friction between them. The second film layer 2-2 adsorbs the positive charges in the second electrode layer 2-1 after friction, correspondingly giving the second electrode layer 2-1 a negative charge.

The second insulating substrate 2-3 is made of a material capable of elastic deformation and has bending resistance. The thickness ratio of the second film layer 2-2 to the thickness of the second insulating substrate 2-3 is 1:0.1-10. The second film layer 2-2 is a self-made film. This thickness ratio of the second film layer 2-2 to the second insulating substrate 2-3 can achieve the blocking of electron transmission. In one embodiment, the second insulating substrate 2-3 is an insulating film, and its material is one or more of the following common polymers with good plasticity: polyacrylic acid, polyethylene terephthalate, polymethyl terephthalate, polyvinyl chloride, polyimide, and nylon. When it is made of two or more materials, the second insulating substrate 2-3 is a copolymer of the above two or more materials. Preferably, the thickness of the second insulating substrate 2-3 is 0.05mm-2.5cm. This thickness range can reduce the volume of the first power generation unit 1 while ensuring electrical safety.

[0053] In one embodiment, an insulating connector 6 may be provided between the first power generation unit 1 and the second power generation unit 2; the insulating connector 6 is used to provide deformation space between the first power generation unit 1 and the second power generation unit 2. Alternatively, the insulating connector 6 may not be used, and the first power generation unit 1 and the second power generation unit 2 may be configured as a curved structure, as long as deformation space is ensured between them. The structure of the triboelectric power generation device using the insulating connector 6 to connect the first power generation unit 1 and the second power generation unit 2 is shown below. Figure 1This is a vertically separated triboelectric nanogenerator. Under the influence of mechanical energy such as pressing or striking, both the first power generation unit 1 and the second power generation unit 2 generate triboelectric currents, converting mechanical energy into electrical energy. This triboelectric generator can power small electrical devices such as sensors and LED lights, and can be used for portable applications in the field. The sensor can be a passive sensor capable of real-time qualitative detection of gases.

[0054] To increase power generation, in one embodiment, multiple generators may be provided, connected in parallel. The optimal number of generators is 2 to 1000.

[0055] This invention utilizes mechanical energy to induce elastic deformation in a generator. During this deformation, triboelectric charging occurs within the generator. A film layer capable of adsorbing negative charges and a film layer capable of adsorbing positive charges then adsorb these charges respectively. This results in a first electrode layer carrying a positive charge and a second electrode layer carrying a negative charge. The potential difference between the negative and positive charges provides electrical energy to external power components. Using this triboelectric generator to power power components eliminates the need for batteries, enabling long-term power supply for field detection and early warning equipment. This reduces battery usage and minimizes the impact of discarded batteries on biological growth and reproduction, as well as on normal human life.

Figure 5 As shown, the triboelectric generator can operate for a long time and can be converted into a constant voltage output after being rectified by an integrated rectifier circuit.

[0064] The triboelectric generator and the integrated rectifier circuit together constitute the energy conversion component 8, which serves as the power source in the circuit. It is connected in series with the sensing and display components. The detailed circuit diagram is as follows: Figure 6As shown. The display component includes 12 red LEDs and an adjustable resistor. Adjusting the resistance of the adjustable resistor adapts to the power of the energy conversion component, ensuring the LEDs light up smoothly when the current in the circuit changes. The components are connected by wires. Sensing component 7 is a resistive ammonia gas sensor; its resistance decreases when ammonia gas is introduced. When 100 ppm of ammonia gas is introduced, four LEDs light up.
