Method and device for preparing friction nanometer generator based on 3D printing

Abstract

The invention discloses a method for preparing a friction nanometer generator based on 3D printing. The method comprises the steps that printing ink is prepared, specifically, a liquid matrix material is doped with a functional material, and a delayed coagulant and a thickening agent are selectively added, so that the solidification time and viscosity of the obtained printing ink are adjusted and controlled; the functional material is used for preparing each part of the friction nano generator; and 3D printing is sequentially performed on a substrate by the aid of the printing ink according to the manufacturing sequence of each part of the friction nanometer generator, so that the friction nanometer generator is prepared; the printing ink is in a liquid state before printing and is cured after printing for a preset time, and the shape of the printing ink is kept unchanged. The invention further discloses a 3D printing device, the friction nanometer generator prepared by the preparation method and wearable equipment.

Description

technical field [0001] The disclosure belongs to the technical field of energy device preparation, and relates to a method and device for preparing a friction nanogenerator based on 3D printing, and also relates to a friction nanogenerator and a wearable device prepared by the above preparation method. Background technique [0002] The development of information energy technology closely affects the progress of social economy and industry. The current social energy and environmental issues are still the bottleneck that restricts sustainable development. From another perspective, the popularity of the Internet of Things will inevitably bring about the vigorous development of sensor networks. The energy supply problem of distributed sensors has always been one of the obstacles limiting the development of this type of technology. In 2012, the new green energy harvesting method - Triboelectric Nanogenerator (TENG) can not only effectively collect the mechanical energy in the e...

Problems solved by technology

The energy supply problem of distributed sensors has always been one of the obstacles restricting the development of this type of technology.

[0003] However, the current triboelectric nanogenerators mainly rely on manual experimental equipment for preparation, especially flexible and wearable energy harvesting devices, which bring many uncertain factors in the large-scale preparation and assembly process.

Experiments have found that with the same material and equipment, the output performance of non-flexible frictional nanogenerators prepared in different ways varies greatly. Therefore, it is urgent to propose a process that can realize one-stop fabrication of frictional nanogenerators to promote industrial production.
