Problems solved by technology

[0003] There are two main disadvantages in the existing friction generators: on the one hand, two kinds of friction materials in a planar shape rub against each other, the friction area is relatively small, the friction effect is relatively weak, and the output performance of the device includes low output voltage and output power. It is not conducive to integration and promotion; on the other hand, the device as a whole does not have tensile properties. When the device is stretched or bent, the generator cannot work, and the versatility is poor, which limits the use of triboelectric generators in complex environments and human-machine interfaces.

Embodiment Construction

[0050] The invention provides a triboelectric generator based on a wrinkled conductive film and a preparation method thereof. By preparing the conductive thin film material of the electrode part of the triboelectric generator into a wrinkled shape, and cooperating with a flexible substrate as an insulating layer, the friction area is increased and friction effect, and also improved the ductility of the device. On the one hand, the output voltage and output power of the friction generator were effectively improved, and the integration and popularization of the device were improved; on the other hand, the traditional friction generator was expanded. The power generation method can generate power through pressure, stretching and bending, which further enhances the versatility of the device and helps to broaden the application of friction generators in complex environments and human-machine interfaces.

Abstract

The present invention provides a friction generator based on a folded conductive film. The friction generator comprises an upper friction layer which comprises an upper insulating layer (200) made of a flexible material and an upper electrode (100) on the upper insulating layer, a lower friction layer which comprises a substrate (400) made of a flexible material and a lower electrode (300) which is on the substrate and is made of a folded conductive film material. According to the folded design, a friction area and a friction effect are improved, thus a device with a same area has larger output voltage, in a same space structure, the output voltage and output power of the friction generator are effectively improved, the integration and promotion of multiple friction generators are facilitated, the scalability of a device is also improved through folded electrodes in upper and lower positions, thus a power generation mode is broadened, power can be generated through pressure, power can be generated through drawing and bending, the versatility of the device is enhanced, and the application of the friction generator in the aspects of complex environment and the man-machine interface is facilitated.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a friction generator based on a wrinkled conductive film, a preparation method and an integrated structure. Background technique [0002] Energy is an integral part of electronic devices. In the process of the development of electronic devices towards mobile, portable and wearable, traditional energy technologies such as lithium batteries can no longer meet the demand. The use of trillions of batteries distributed around the world With a limited lifetime, managing, replacing, recycling and reusing batteries can be a daunting task. As the heart of the next generation of flexible electronic devices, it needs to be portable and sustainable, and the emergence of the triboelectric nanogenerator makes it possible. The friction generator is a new energy harvesting method, and it is also a new power generation terminal. It is a potential stock to solve the global energy shortage and pr...
