Fiber-based pressure/temperature sensors are highly desired in wearable electronics because of their natural advantages of good breathability and easy integrability. However, it is still a great challenge to fabricate reliable and highly sensitive fiber-based pressure/temperature sensors via a scalable and facile strategy. Herein, a novel fiber-based iontronic sensor with excellent pressure-and temperature-sensing capabilities is designed by assembling two crossed hollow and porous ionogel fibers filled with liquid metal. Serving as a pressure sensor, a high detection resolution (1.16 Pa), a high sensitivity of 13.30 kPa −1 (0−2 kPa), and a wide detection range (∼207 kPa) are realized owing to its novel hierarchical structure and the selection of deformable liquid electrodes. As a temperature sensor, it exhibits a high temperature sensitivity of 25.99% °C−1 (35−40 °C), high resolution of 0.02 °C, and good repeatability and reliability. On the basis of these excellent sensing capabilities, the as-prepared sensor can detect not only pressure signals varied from weak pulse to large joint movements but also the proximity of different objects. Furthermore, a large-area fiber array can be easily woven for acquiring the pressure mapping to intuitively distinguish the location, magnitude, and shape of the loaded object. This work provides a universal strategy to design fiber-shaped iontronic sensors for wearable electronics.

“…[17,18] In contrast, yarn-based TENG (Y-TENG) has attracted wide attention due to its high degree of mechanical freedom and flexibility, which can be further integrated into textile-based TENG (T-TENG) through traditional techniques (sewing, knitting, weaving, etc.). [19,20] T-TENG, which combines the advantages of textiles for its breathability, washability, flexibility, lightweight, and capability of TENG for its energy harvesting and versatile sensing ability, has been considered as a significant solution for wearable electronics and intelligent housing systems. [21][22][23][24][25][26] However, due to the flammability of textile materials, most T-TENGs are susceptible to fire damage and even cause fire spread and human injury.…”

With the rapid development of the textile-based triboelectric nanogenerators (T-TENGs), it is highly desired to create a simple and cheap fabrication strategy for the T-TENGs with high flame-retardant performances (FRT-TENGs), which can present reliable electrical performance in the fire disaster. In this work, by covering the flame-retardant polyethylene terephthalate filaments around the conductive fiber, a flame-retardant triboelectric yarn is successfully developed through a simple and continuous high-speed braiding process. The obtained composite yarns are further woven into an FRT-TENG, which presents excellent comprehensive performances, including good energy harvesting ability, long-term durability and washability, excellent flame retardancy, and high comfortability. The open-circuit voltage (V OC ) and short-circuit current (I SC ) can reach nearly 12 V and 0.36 μA, respectively. The FRT-TENG shows a high limiting oxygen index value of 31.3% and self-extinguishing behavior, and still presents high energy output performances after the burning, making it a perfect candidate for intelligent devices with high fireproof ability, such as the smart firefighter uniform and the intelligent carpet for escape direction indication.

Micro/nanostructures can increase effective surface area and enhance the performance of wearable devices, such as the sensitivity of sensors and output of triboelectric nanogenerators. Empowering commercial fibers and fabrics with durable and robust micro/nanostructures has become a major research concern for sustainable wearables. Many technologies are developed to fabricate micron/nanostructures on fibers and textiles, such as breath figure method, electrospinning, and direct imprinting thermal drawing. However, most of these methods have their own limitations toward mass production and real‐life application, including poor solvent resistance, time assuming, requiring expensive equipment, and limited capacity for post‐adjustment of commercial textiles. Here, a plasma‐enhanced breath figure (PEBF) technique to fabricate solvent‐tolerant microporous structure on existing fabrics with tailored pore size is developed. By combining the wearable nature of fabrics and the surface engineering power of PEBF, the fabricated solvent‐tolerant microporous fabric offers excellent flexibility, washability, breathability, and suitability for large‐scale production, as well as the advantages of cost effectiveness and fast production. Furthermore, wearable triboelectric nanogenerators based on solvent‐resistant microporous structured fabrics, revealing the bright future of the PEBF technology in wearable devices and smart textiles are fabricated.
