The invention relates to the field of flexible intelligent wearable power generation and sensing, in particular to a preparation method of a multi-mode coexisting coaxial tubular friction nano-generator, which comprises the following steps of: 1, preparing a compression springback framework; 2, preparing an electrostatic induction electrode; 3, preparing a dielectric electrode; 4, preparing a coaxial electrification electrode; 5, assembling the electrodes obtained in the step 4 and the step 3, enabling the electrodes to be coaxial, and fixing the two ends of the electrodes to obtain a coaxial tubular friction nanometer generator; the working mechanism of the multi-mode coexistence coaxial friction nano-generator prepared by the method comprises a single electrode mode and a contact separation mode; an electrode in the single electrode mode is woven into a tube by adopting heat-setting filaments and is set by utilizing a heat-setting process, so that the tube has high elasticity and elastic recovery; the heat-setting filament adopted by the invention has a skeleton effect, and the problems of small output electric signal, short service life, low combination degree with textiles and the like of the one-dimensional linear friction nano generator are solved.
Description
technical field [0001] The invention relates to the field of flexible intelligent wearable power generation and sensing, in particular to a preparation method of a multi-mode coexisting coaxial tubular triboelectric nanogenerator. Background technique [0002] Triboelectric nanogenerators (TENGs), as an efficient technology to convert human or external mechanical energy into electrical energy, provide a new approach for wearable self-powered sensors. It has the advantages of large output electrical signal, long service life, and high degree of integration with textiles. [0003] At present, the triboelectric nanogenerator products on the market are mainly two-dimensional plane or three-dimensional devices, and the energy-supplying devices are bulky, not suitable for portable wear, and cannot be incorporated into textiles. It is well known that there are four working modes of triboelectric nanogenerators, including single electrode mode, contact separation mode, sliding fric...
