The multi-physical-field nanometer generator structurally comprises an outer electrode, an inner electrode, the carbon nanometer tube thin film and a silicon substrate composite substrate and is characterized in that when the carbon nanometer tube thin film is subjected to the combined action of light and airflow, solar energy and fluid mechanical energy are converted into electric energy with the photothermal effect, the Bernoulli effect and the Seebeck effect. The multi-physical-field nanometer generator comprises p type or n type electricity generating units which are connected in series or in parallel to form a matrix power supply device which is provided with a plurality of energy output nodes, the number of the electricity generating units can be flexibly set according to different load requirements, and the output power of the generator is improved. The multi-physical-field nanometer generator has the advantages of being tiny in size, high in reliability, flexible, practical, free of moving parts and the like, and capable of being applied to skins of vehicles such as automobiles, trains, planes. Electricity can be provided for internal micro-nano mechanical and electrical systems or devices by utilizing light and air flow.

Problems solved by technology

[0005] Therefore, the use of carbon nanotube films to prepare multi-physics field nanogenerators has attractive application prospects, which can solve at least two problems: one is that the current generated by a single carbon nanotube is usually weak, and it cannot achieve stable and continuous power supply. Second, the application of nanogenerators is usually a complex environment with multiple physical fields such as light, heat, and fluid. The power generation characteristics under a single physical field are easily affected by external conditions, which has certain limitations. At the same time, it cannot comprehensively utilize the solar energy in the environment. , wind energy and other energy

Compared with solar or wind power generation systems alone, complementary power generation systems can generate electricity around the clock, and have higher power generation and stability. limited its scope of application
