Problems solved by technology

[0005] The multi-layer structure used by traditional triboelectric nanogenerators is not easy to be stretched and twisted, so it is difficult to directly match with wearable devices

At the same time, in order to improve the output efficiency of the friction generator, the surface of the friction layer is usually structured, which makes the friction layer easy to be worn during work, and makes the generator difficult to be packaged and susceptible to the influence of environmental humidity.

In addition, the triboelectric charge of the traditional triboelectric generator is mainly concentrated on the surface of the material, while the bulk effect of the material (referring to the internal deformation of the material and the interaction of components under the action of external force) has not been utilized.

[0006] Therefore, in order to solve the problems that the traditional nano triboelectric generator is not easy to be stretched and twisted, it is difficult to directly match with wearable devices, the friction layer is easily worn and the body effect is not used, it is necessary to invent a simple structure, anti-deformation Highly capable new flexible nanotriboelectric generator
