A kind of cuttable flexible wire, its preparation device and preparation method

Abstract

The invention provides a cuttable flexible wire, which is composed of liquid metal and elastic body, and liquid metal particles are dispersed in the elastic body. After the flexible wire is cut, the liquid metal material will not flow out, and it can withstand deformations such as stretching and bending. When deformations such as stretching and bending occur, its resistance will basically not change. The present invention also provides a device capable of preparing a large-scale cuttable flexible wire, including a material mixing device, a current detection device, a conductor pipeline, a protective layer pipeline, and a heating device, and the performance of the cuttable flexible wire prepared by the device is Stable, large tensile strain, recoverable after stretching, and the wire can be cut, which has potential application value in flexible electronics.

Description

technical field [0001] The invention relates to the technical field of flexible electronics, in particular to a cuttable flexible wire, a preparation device and a preparation method thereof, and has broad application prospects in the fields of interconnection of flexible electronic devices, flexible wires and the like. Background technique [0002] In recent years, with the rise of wearable and implantable devices, flexible electronics has received more and more attention worldwide. In 2000, "Science" magazine listed flexible electronics as one of the "Top Ten Emerging Technologies in the 21st Century", and in 2010, "Electronic Engineering Times" listed flexible electronics technology as one of the "Top Ten Emerging Technologies in the World". [0003] In order to achieve full flexibility of electronic devices, conductive lines and wire materials, as an integral part of electronic devices, also need to be flexible.

AI Technical Summary

Problems solved by technology

[0004] Currently there are mainly the following types of flexible wires: 1. Flexible wires prepared by compounding solid conductive fillers and elastic materials, but the conductivity of the flexible wires prepared by this method changes greatly during the stretching process; 2. Ionic conductor type flexible wires Wire, although the flexible wire prepared by this method has a large stretching rate, the resistance changes greatly during the stretching process, and the preparation process is complicated; 3. The liquid metal is injected into the elastic material tube to form an elastic material as the tube wall to wrap the liquid metal Although the flexible wire structure prepared by this method is relatively large, once the flexible wire is cut, the liquid metal will overflow, so the flexible wire cannot be cut, and it is difficult to produce in large quantities
