Wearables and bioelectronics rely on breathable interface devices with bioaffinity, biocompatibility, and smart functionality for interactions between beings and things and the surrounding environment. Elastic fibers/fabrics with mechanical adaptivity to various deformations and complex substrates, are promising to act as fillers, carriers, substrates, dressings, and scaffolds in the construction of biointerfaces for the human body, skins, organs, and plants, realizing functions such as energy exchange, sensing, perception, augmented virtuality, health monitoring, disease diagnosis, and intervention therapy. This review summarizes and highlights the latest breakthroughs of elastic fibers/fabrics for wearables and bioelectronics, aiming to offer insights into elasticity mechanisms, production methods, and electrical components integration strategies with fibers/fabrics, presenting a profile of elastic fibers/fabrics for energy management, sensors, e‐skins, thermal management, personal protection, wound healing, biosensing, and drug delivery. The trans‐disciplinary application of elastic fibers/fabrics from wearables to biomedicine provides important inspiration for technology transplantation and function integration to adapt different application systems. As a discussion platform, here the main challenges and possible solutions in the field are proposed, hopefully can provide guidance for promoting the development of elastic e‐textiles in consideration of the trade‐off between mechanical/electrical performance, industrial‐scale production, diverse environmental adaptivity, and multiscenario on‐spot applications.

“…First, a suitable carbon substrate is essential for the stable anchoring of highly dispersed N and Fe atoms. Graphene with unique physicochemical properties has demonstrated exceptional electrochemical properties as carbon substrates for metal nanoparticles. − It can provide a large-scale continuous conductive network to enhance the conductivity and a large surface area allowing more metal nanoparticles to be dispersedly anchored, as well as it can act as an interfacial barrier to metal nanoparticles with a good confinement effect. , Chitosan, a natural biomass material rich in amino functional groups, is usually considered as an attractive precursor for N-doped porous carbon . Therefore, the carbon substrates constructed synergistically using graphene and chitosan are desirable, with satisfactory long- and short-range synergistic conducting networks, a large surface area, and an abundant pore structure, enabling N-doping and dispersed anchoring of ultrafine iron-based nanoparticles, facilitating charge/ion transport and storage during CDI.…”

Developing a high-performance Cl-storage electrode is a crucial issue for capacitive deionization (CDI). Iron-/nitrogen-doped carbon hybrid composites with densely dispersed ultrafine Fe-based nanoparticles are promising candidates for Cl-storage electrodes, yet further improvement of Fe-based nanoparticles prone to agglomeration is strongly desired. Hereby, a hybrid electrode with ultrafine iron carbide nanoparticles encapsulated in graphene/chitosan-derived N-doped carbon (Fe 3 C@GNC) is successfully constructed via facile one-step pyrolysis of aerogel composites. The encapsulation effect of graphene can effectively confine Fe 3 C nanoparticles in the carbon matrix, enabling stable and dispersive ultrafine Fe 3 C nanoparticles, and chitosan also enables N-doping. Also, a satisfactory conductive system with synergistically long-and short-range conductive networks is successfully generated by the graphene/N-doped carbon matrix. The Fe 3 C@GNC electrode exhibits a typical pseudocapacitive behavior, with a specific capacitance of up to 305.33 F g −1 and a dominant capacitive contribution of up to 96%. As a Cl-storage electrode for CDI, it delivers a Cl − adsorption capacity as high as 82.08 mg g −1 with a retention rate of 74.2% for 150 cycles. Furthermore, it is revealed that the Cl − storage mechanism of Fe 3 C@ GNC is a pseudocapacitance effect induced by the reversible Fe 2+ /Fe 3+ redox couple, which can achieve fast reaction kinetics and structural stability in the CDI process.
