Flexible and stretchable electronics is a research hotspot in the field of electronics, and progress has been made in applications such as flexible displays, electronic skins, flexible sensors, and implantable medical devices. In the process of constructing various flexible and stretchable electronic devices, it is necessary to rely on the connection of elastic conductors that still maintain a good electrical conductivity under different deformation conditions, so the preparation of ultra-high elastic wires becomes the key to the development of flexible electronic devices. In recent years, the main method for researchers to prepare elastic conductors is to build conductive materials into shape structures that can release pre-strain. On the one hand, flexible conductive substrates can be used to build various conductive materials into corrugations; secondly, micro-machining is directly adopted. The photolithography and electron beam deposition methods are configured. Although certain results have been achieved, the above-mentioned methods still have the disadvantages of being time-consuming and difficult to mass-produce, and most of the prepared elastic electrical conductors can only maintain good electrical conductivity within a moderate strain range (<200%).

Recently, the research team led by Sun Jing, a researcher at the Shanghai Institute of Ceramics, Chinese Academy of Sciences, successfully prepared a high-conductivity elastic conductive fiber with ultra-high elasticity (>500%). The elastic conductive fiber was subjected to various harsh external deformation conditions. It is still able to maintain excellent electrical conductivity and has broad application prospects in the field of flexible electronics. This work was published in the journal ACS NANO and has applied for a Chinese invention patent.

The research team used a double spiral covered yarn as an elastic scaffold material. The silver nanowires were evenly coated on the surface of the cotton fiber as a conductive material by a dip coating method. The conductivity of the resulting elastic conductive fiber can be as high as 4000 S/. Cm, and the electrical conductivity can still be maintained at 688 S/cm under the strain conditions of stretching up to 500%. Under the cyclic deformation test, the conductivity was stable at 188 S/cm after 1000 times of 200% strain tensile deformation. After 1000 bending deformations, the conductivity remained stable. In the application demonstration, the research team used elastic conductive fibers as a wire system to directly integrate LED arrays on a flexible polymer substrate. The obtained LED arrays can maintain stable operation under various deformations such as stretching and bending. The application potential of this elastic conductive fiber in a large area of ​​flexible electronics is shown. The research team also demonstrated the biological compatibility of the elastic conductive fiber by implanting subcutaneously on the back of mice, which laid the foundation for its application in the field of implantable flexible devices.

Once this work was published, it attracted international attention. Science made a special report on the recent science and technology news page.

The work was funded by the National Key Basic Research Development Program, the National Natural Science Foundation of China, the Shanghai Natural Science Foundation and the Shanghai Institute of Ceramics, Chinese Academy of Sciences.
