Recent Advances in Fiber-Shaped Electronic Devices for Wearable Applications

Abstract

Fiber electronics is a key research area for realizing wearable microelectronic devices. Significant progress has been made in recent years in developing the geometry and composition of electronic fibers. In this review, we present that recent progress in the architecture and electrical properties of electronic fibers, including their fabrication methods. We intensively investigate the structural designs of fiber-shaped devices: coaxial, twisted, three-dimensional layer-by-layer, and woven structures. In addition, we introduce remarkable applications of fiber-shaped devices for energy harvesting/storage, sensing, and light-emitting devices. Electronic fibers offer high potential for use in next-generation electronics, such as electronic textiles and smart integrated textile systems, which require excellent deformability and high operational reliability.

Wearable energy storage with MXene textile supercapacitors for real world use

“…[1][2][3] A subeld of these wearables, known as electronic textiles or e-textiles, integrates conformable electronics with traditional so goods. [4][5][6] E-textiles have relevance across a range of technologies like Internet of Things (IoT), extended reality 7 and especially healthcare, where remote 8 and in-person care 9 can benet greatly from prolonged wireless monitoring using so, human-friendly materials.…”

Strain-Insensitive Stretchable Fiber Conductors Based on Highly Conductive Buckled Shells for Wearable Electronics

“…Fiber electronics have emerged as a strategy for realizing wearable applications owing to their advantages, such as their human-friendly interfaces, convenient wearability, and lightweight, compared with other state-of-the-art electronics. − Highly stretchable fiber conductors are valuable electrodes that can bridge the diverse components in fiber electronics. Stretchable fiber conductors are generally fabricated employing conductive materials/polymer composites − or encapsulated liquid metals. − However, the applications of existing stretchable fiber conductors in wearable electronics were limited by the degradation of their electrical conductivities via the loss of contact between conductive materials, following external deformations according to Poisson’s ratio .…”

Organic light‐emitting fibers and fabrics for truly wearable smart displays: Recent progress and future opportunities

“…To realize textile displays, two approaches have been universally used: One is the fiber‐based approach (a cylindrical shape with a very long length compared to width), and the other one is the fabric‐based approach (a textile in the form of woven fibers) 14–18 . In the fiber‐based approaches, the electronics are implemented on one strand of the fiber and then woven together to form a textile.…”

“…[7][8][9][10][11][12][13] To realize textile displays, two approaches have been universally used: One is the fiber-based approach (a cylindrical shape with a very long length compared to width), and the other one is the fabric-based approach (a textile in the form of woven fibers). [14][15][16][17][18] In the fiberbased approaches, the electronics are implemented on one strand of the fiber and then woven together to form a textile. It is worth noting that the fiber provides advanced deformability, thanks to the cylindrical shape of the fiber, as well as other natural advantages including porosity and lightweight.…”
