Hydrogels are considered as promising materials for human‐machine interfaces (HMIs) owing to their merits of tailorable mechanical and electrical properties; nevertheless, it remains challenging to simultaneously achieve ultrasoftness, good mechanical robustness and high sensitivity, which are the pre‐requisite requirements for wearable sensing applications. Herein, for the first time, this work proposes...
MXene nanosheets are believed to be an ideal candidate for fabricating fiber supercapacitors (FSCs) due to their metallic conductivity and superior volumetric capacitance, while challenges remain in continuously collecting bare MXene fibers (MFs) via the commonly used wet‐spinning technique due to the intercalation of water molecules and a weak interaction between Ti3C2TX nanosheets in aqueous coagulation...
Flexible electronics have gained great attention in recent years owing to their promising applications in biomedicine, sustainable energy, human‐machine interaction, and toys for children. Paper mainly produced from cellulose fibers is attractive substrate for flexible electronics because it is biodegradable, foldable, tailorable, and light‐weight. Inspired by daily handwriting, the rapid prototyping...
Thanks to their light-weight, wearing comfort, and amenability to be woven into textiles, solid-state fiber supercapacitors (FSCs) have been considered as promising energy storage devices for wearable electronics. Carbon fibers (CFs) have the merits of both superior mechanical strength and conductivity, excellent flexibility, doped by heteroatoms, good knittability/weavability, and most importantly...
As an essential member of 2D materials, MXene (e.g., Ti3C2Tx) is highly preferred for energy storage owing to a high surface‐to‐volume ratio, shortened ion diffusion pathway, superior electronic conductivity, and neglectable volume change, which are beneficial for electrochemical kinetics. However, the low theoretical capacitance and restacking issues of MXene severely limit its practical application...
