Abstract

The invention provides a stretchable friction nano-power generator and a preparation method thereof. The stretchable friction nano-power generator comprises: a stretchable electrification layer, wherein the stretchable electrification layer is internally provided with a closed cavity, the cavity is suitable for being filled with a liquid metal, the closed cavity comprises a first cavity body and aplurality of pore channels distributed in the circumferential direction of the first cavity body, and the liquid metal is suitable for flowing between the pore channels and the first cavity body; andan electrode layer suitable for being connected with the surface of the stretchable electrification layer. According to the invention, the stretchable electrification layer can be stretched and released in multiple directions, so that the liquid metal flows back and forth between the first cavity and the pore channels, induced charges are generated on the surface of the stretchable electrification layer, and compared with the prior art, the limitation of electric performance output of the power generator in the output direction is eliminated, and the electric energy output capability of the power generator is improved.

Description

technical field [0001] The invention relates to the technical field of frictional nanometer generators, in particular to a stretchable frictional nanometer generator and a preparation method thereof. Background technique [0002] Triboelectric nanogenerator is a new type of self-driven energy harvesting device, which uses the coupling of triboelectric effect and electrostatic induction effect to convert tiny mechanical energy into electrical energy. Due to their simple design, wide material selection, and high output performance, they have been widely used in flexible and stretchable energy sources. Among them, stretchable triboelectric nanogenerators have important applications in flexible electronics and wearable devices. [0003] At present, most of the stretchable generators are generally based on the following two structures: first, using the pretreated wrinkled electrification layer to effectively contact and separate during the stretching process to achieve electrica...
