Description

technical field [0001] The invention relates to the energy field, in particular to a rotary friction nanometer generator. Background technique [0002] Electrification by friction is the result of the transfer of electrons from one object to another, so that both objects are charged with an equal amount of charge. Objects that gain electrons are negatively charged, and objects that lose electrons are positively charged. Therefore, when two uncharged objects rub against each other, they will be charged. Triboelectricity is one of the most common phenomena in nature. By rubbing objects against each other, one side will be charged negatively, and the other side will be negatively charged. It is positively charged, but triboelectricity is difficult to collect and utilize, so it is often ignored. In the prior art, a transparent flexible triboelectric generator has been developed. The triboelectric nanogenerator can not only be used to collect the original Various forms of mecha...

Therefore, when two uncharged objects rub against each other, they will be charged. Triboelectricity is one of the most common phenomena in nature. By rubbing objects against each other, one side will be charged negatively, and the other side will be negatively charged. It is positively charged, but triboelectricity is difficult to collect and utilize, so it is often ignored. In the prior art, a transparent flexible triboelectric generator has been developed. The triboelectric nanogenerator can not only be used to collect the original Various forms of mechanical energy are wasted (harvesting ocean energy, wind energy, vibration energy, etc.), and can also be used as a self-driven sensor to detect mechanical signals, however, the existing friction generator works on the working principle of the generator During the process, the friction surface is formed between the polymer and the metal electrode, or between the polymers. The friction surface needs to be in constant contact and separation, but due to the roughness of the material surface, the contact is incomplete, resulting in conversion The efficiency is very low, and the functions of energy harvesting and detection cannot be realized
