A kind of preparation method of flexible coaxial wire

Abstract

The invention provides a flexible coaxial wire, comprising a conductive core and an electrostatic spinning film wrapped on the outer surface of the conductive core, wherein the material of the conductive core is a flexible conductive material, and the material of the electrostatic spinning film is a flexible polymer insulating material. The flexible coaxial conductor has the advantages of good flexibility, high conductivity, external insulation, super-flexibility and super-lightness. And the flexible coaxial conductor has excellent stability and human body adhesion, With electrospun film as insulation layer, it also has excellent biocompatibility and can be directly bonded to skin. It shows a broad application prospect in the integration of wearable electronics, such as personal medical monitoring, human motion detection, human-machine interaction, virtual reality entertainment technology and so on.

Description

technical field [0001] The invention relates to the technical field of flexible and wearable electronics, and more particularly, to a method for preparing a flexible coaxial wire. Background technique [0002] In recent years, wearable electronic devices have developed rapidly and become an important trend in the development of next-generation electronic products. As an important branch of wearable electronic devices, flexible wires play an important role in the integration of wearable electronics. Conductive connecting wires between wearable electronic devices should have certain characteristics such as mechanical flexibility, high bendability, high durability, biocompatibility, external insulation, waterproof, etc. to achieve their wearable characteristics and their ability to operate in individuals. Wide applications in medical treatment, motion detection, human-computer interaction, virtual reality entertainment technology, etc. [0003] However, the traditional materi...

Problems solved by technology

[0003] However, the traditional materials based on metal wires, because their external insulating materials are usually hard resins, plastics, etc., so the overall rigidity is relatively large; and the traditional wires are not oriented to the application of flexible wearable devices, so the size (diameter) is also large

The above two points lead to the inconvenient bonding of traditional wires with flexible electronic devices, and cannot meet the requirements for the integration of flexible and wearable electronic devices
