Cuttable flexible wire and preparation device and preparation method thereof

Abstract

The invention provides a cuttable flexible wire which is composed of liquid metal and an elastomer, wherein liquid metal particles are dispersed in the elastomer. The liquid metal material will not flow out after the flexible wire is cut, and can bear stretching, bending and other deformation. When the liquid metal material produces stretching, bending or other deformation, the resistance will not change. The invention further provides a device for large-scale preparation of the cuttable flexible wire, comprising a mixing device, a current detection device, a conductor pipe, a protective layer pipe, and a heating device. The cuttable flexible wire prepared using the device has stable performance and large tensile strain, can be recovered after stretching, and can be cut. The cuttable flexible wire has potential application value in the flexible electronic technology.

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.

[0004] Currently there are mainly the following types of ...
