Thermally drawn advanced functional fibers: New frontier of flexible electronics

Enhanced laser action from smart fabrics made with rollable hyperbolic metamaterials

“…To be integrated onto human body, these devices must be biocompatible and be able to withstand mechanical deformation and different bending curvatures 3,4 . This promising market of wearable photonics and optoelectronics has inspired a number of demonstrations such as flexible photodetectors 5 , stretchable laser systems 6 , artificial electronic skins 3 , paper-based memory devices 7 , and flexible optoelectronic fibers and textiles [8][9][10][11] . The developed flexible photonic devices possess advanced functionalities beyond their rigid counterparts.…”

In-Fiber Structured Particles and Filament Arrays from the Perspective of Fluid Instabilities

“…Further improvements can be realized by the optimization of fiber fabrication process such as controlling the drawing stress to achieve a more uniform fiber core, which will lead to a smaller variation of the resulting sphere sizes. Moreover, the ability to induce a precisely tunable built-in stress onto spherical particles and to form in-fiber homo-and heterojunctions may offer a substantial impact on future developments of photonic, electric, thermoelectric devices, and other related fields [11][12][13].…”

“…Moreover, the filamentation instability of a stretching sheet during thermal drawing clearly offers more opportunities to explore fluid instability, and unconventional sophisticated nanostructures might be achieved through designing structures such as filamentation in two adjacent sheets or three-layer sandwiched sheets. By utilizing the available toolbox of various materials combination (such as semiconductors, metals, and polymers) compatible with thermal drawing, more versatile functional nanodevices are anticipated to be realized in either single fibers or mass-produced in large-scale textiles [11][12][13]49].

“…Over the last decade, this technique has been successfully employed to achieve an altogether different class of multimaterial multi-functional fibers [9]. This specially designed fiber is composed of distinctive components (e.g., semiconductors, insulators, and metals) and complex geometries (e.g., wires, cylindrical shells or layer structures), enabling the sophisticated integrated functionalities (e.g., electronic, optoelectronic, and acoustic), at either a single-fiber level or in large-scale fabrics and textiles, for a broad range of applications in biomedical, optoelectronic and micro/nano technologies [9][10][11][12][13].…”
