“…In addition to the heating temperature, sensitivity and stability are also important parameters to measure the heating capacity of electrothermal fabrics. ,, Therefore, we studied the effect of switching voltage on the electrothermal performance of conductive protein fiber flexible fabric at a 1 V voltage. The surface temperature can rise to 57 °C within 7 s and remains stable (1 V voltage was applied).…”

To meet the diverse needs of humans, smart cloth has become a potential research hotspot to replace traditional cloth. However, it is challenging to manufacture a flexible fabric with multiple functions. Here, we introduce a smart cloth based on liquid metal (LM) conductive fibers. Ga2O3 nanoparticles are obtained through ultrasonic pretreatment. Furthermore, a coordination bond is formed between thiol groups on the surface of protein fibers and Ga2O3 through a scraping method, allowing Ga2O3 particles to be grafted onto the surface of protein fibers in situ. Finally, LM conductive fibers are encapsulated using a photocuring adhesive. In addition, a wearable smart cloth integrated with multiple sensors has been developed based on LM conductive fibers. Users can not only monitor their movement trajectory and the surrounding environment in real time but also have their data supervised by family members through a client, achieving remote and continuous monitoring. The development of this wearable smart cloth provides strong support for future wearable, flexible electronic devices.

“…In many of these existing conductive materials, an inherent tradeoff had to be made in their electromechanical properties in order to allow for their use in textile substrates [ 69 ]. Among these drawbacks is the nonuniform dispersion of filler material within the substrate, leading to aggregates and compromised overall mechanical performance [ 166 ]. On the other hand, some researchers show that coated conductive textile fabrics underperform when using fabric-based textiles with conductive fibers due to unevenness of the substrate (i.e., surface resistivity) [ 82 ].…”

Wearable sensors are rapidly gaining influence in the diagnostics, monitoring, and treatment of disease, thereby improving patient outcomes. In this review, we aim to explore how these advances can be applied to magnetic resonance imaging (MRI). We begin by (i) introducing limitations in current flexible/stretchable RF coils and then move to the broader field of flexible sensor technology to identify translatable technologies. To this goal, we discuss (ii) emerging materials currently used for sensor substrates, (iii) stretchable conductive materials, (iv) pairing and matching of conductors with substrates, and (v) implementation of lumped elements such as capacitors. Applicable (vi) fabrication methods are presented, and the review concludes with a brief commentary on (vii) the implementation of the discussed sensor technologies in MRI coil applications. The main takeaway of our research is that a large body of work has led to exciting new sensor innovations allowing for stretchable wearables, but further exploration of materials and manufacturing techniques remains necessary, especially when applied to MRI diagnostics.

“…In this regard, carbon nanotubes and grapheme oxide have been introduced into the spinning solution, aiming to produce fibers with enhanced strength, durability, and electrochemical properties. [191][192][193][194] Because of the interactions between nanomaterials and the spinning solution, which can occur via intermolecular forces or coordination complexes, the composite fibers' mechanical properties were improved. The extent of this impact could be altered by varying the filler concentration and the spinning technique employed.…”

Spider silk, possessing exceptional combination properties, is classified as a bio‐gel fiber. Thereby, it serves as a valuable origin of inspiration for the advancement of various artificial gel fiber materials with distinct functionalities. Gel fibers exhibit promising potential for utilization in diverse fields, including smart textiles, artificial muscle, tissue engineering, and strain sensing. However, there are still numerous challenges in improving the performance and functionalizing applications of spider silk‐inspired artificial gel fibers. Thus, to gain a penetrating insight into bioinspired artificial gel fibers, this review provided a comprehensive overview encompassing three key aspects: the fundamental design concepts and implementing strategies of gel fibers, the properties and strengthening strategies of gel fibers, and the functionalities and application prospects of gel fibers. In particular, multiple strengthening and toughening mechanisms were introduced at micro, nano, and molecular‐level structures of gel fibers. Additionally, the existing challenges of gel fibers are summarized. This review aims to offer significant guidance for the development and application of artificial gel fibers and inspire further research in the field of high‐performance gel fibers.
