Flexible conductive connecting piece of flexible wire and preparation method thereof

Abstract

The invention provides a flexible conductive connecting piece of a flexible wire and a preparation method thereof. The flexible wire comprises liquid metal. The flexible conductive connecting piece comprises a flexible macromolecule wire, a flexible conductive ring arranged on the periphery of the flexible macromolecule wire in a sleeving mode, and a flexible insulating ring arranged on the periphery of the flexible conductive ring in a sleeving mode. The periphery of one end of the flexible conducting ring is not covered with the flexible insulating ring and is kept exposed. The flexible conductive connecting piece is fixedly connected with the flexible wire, and the exposed end of the flexible conductive ring extends into the flexible wire to be in contact with the liquid metal to form conductive connection. The connecting piece can be in good conductive connection with the flexible wire, has good flexibility and stability, forms a full-flexible structure with the flexible wire, andhas a wide application prospect in the flexible electronic technology.

Description

technical field [0001] The invention relates to the technical field of flexible electronics, in particular to a flexible conductive connector of a flexible wire and a preparation method thereof. Background technique [0002] With the development of flexible electronics and wearable devices, flexible wires have attracted more and more attention due to their stretchability and comfort, and have a wide range of applications in the fields of human-computer interaction, human health / sports monitoring, and smart clothing. Application prospect. [0003] At present, there are mainly three types of flexible wires: (1) flexible wires woven directly from conductive yarns, conductive fibers, etc., which have relatively low conductivity and are not resistant to rubbing and washing; (2) traditional copper wires are wound into spring wires, etc. (3) The flexible wire formed by filling the flexible tube with liquid metal, ionic liquid, etc. has good conductivity and flexibility, but the co...

AI Technical Summary

Problems solved by technology

[0005] (1) Directly use rod-shaped or columnar metal electrodes to connect with liquid metal, and the outer layer is connected and fixed with potting glue, etc.; this method introduces rigid electrodes, thereby destroying the flexibility of liquid metal wires, resulting in uncomfortable use;

[0006] (2) Use conductive adhesive for filling, sealing, and connection; however, the conductive adhesive has poor conductivity and cannot meet the use environment that requires high conductivity
