“…Considering the continuous work of t-TENGs, a high and efficient power output is needed. To date, various approaches have been proposed to improve the output performance of t-TENGs, such as surface modifications, [176][177][178][179][180][181] material optimization, [182][183][184][185][186] device structure improvement, [187][188][189][190][191] circuit management, [192] and environmental improvement. Surface/ interface modification is utilized to enhance the effective contact area by introducing nanostructures, such as nanoparticles, nanorods, nanowires, and nanopatterns, which can increase the surface charge densities of the interfaces.…”

Textile‐based triboelectric nanogenerators (t‐TENGs) possess the unique wearability characteristics of fabrics. The advent of t‐TENGs not only broadens the development direction of new materials in the textile industry but also endows TENGs with greater application potential. However, the electrical output and desired comfort properties of t‐TENGs remain limited and impractical. Important progress has been made in the exploitation of t‐TENGs in recent years. In this review, the basic classifications of comfort, including sensorial and tactile comfort, fit comfort, heat–moisture comfort, and appearance aesthetics, are introduced. Combining the wearability of textiles, the recent progress in the development of comfortable t‐TENGs is systematically summarized and discussed from the following aspects: tactile comfort of t‐TENGs, stretchability of t‐TENGs, breathability of t‐TENGs, washability of t‐TENGs, aesthetics of t‐TENGs, and multifunctionality of t‐TENGs. Additionally, the enhanced output performance, power management, integration strategies, and mass production of t‐TENGs are discussed, and the main applications of wearable t‐TENGs are described. Finally, the existing challenges and future research direction of t‐TENGs are presented, which may contribute to promoting further research and applications of wearable t‐TENGs.

“…Furthermore, most T-TENGs were fabricated by coating, electrospinning, electrospraying, and other techniques, which attached some conductive and frictional materials to the yarn and fabric. [36][37][38][39][40][41][42] Due to the variable bending structure and uneven surface characteristics of textiles, the coating on T-TENG is easy cracking/ delamination, leading to low abrasion resistance and poor durability. [43][44][45][46][47][48] Because the complex and time-consuming chemical preparation process is neither economical nor environmentally friendly, it is difficult to mass-produce with existing textile manufacturing technology.…”

With the development of energy‐harvesting fabrics, woven structured textile‐based triboelectric nanogenerators (T‐TENGs) are widely proposed. However, most T‐TENGs with woven structures consist of one material, which greatly limits the functionality of T‐TENGs. This work focuses on structural design and rational material configuration to realize versatility of woven‐structured T‐TENG by a green, eco‐friendly, scalable production method. A 3D triboelectric nanogenerator fabric (3D SP‐FTENG) is proposed, which performs excellent electrical output (27.33 V, 1.76 µA, and 61.6 mW m−2) and wearability (directional water transport and breathability) as well as antibacterial activity. Moreover, in contrast to the previously reported multilayer T‐TENGs which are constructed by directly stacking multilayer functional fabrics together, the fabric interface of this new structure fabricated by weaving the support area and the functional area together is not easily delaminated. The 3D SP‐FTENG demonstrates outstanding durability (machine washability and ultrahigh abrasion resistance). In addition, the SP‐FTENG is able to drive wearable electronics and be used as a self‐powered sensor, such as constantly monitoring the movement signals of human body. This study presents a novel and sustainable strategy for the development of eco‐friendly multifunctional T‐TENGs.

Triboelectric nanogenerators (TENGs) have recently enjoyed rapid development due to their easy fabrication, stable outputs, and wide range of applications. By combining conventional textiles with TENGs, textile-based TENGs (t-TENGs) can be employed with wearable devices and smart textiles. The t-TENGs with a yarn structure, triboelectric yarns, can be directly used to conduct energy conversion and be processed into other energy-harvesting textile structures due to their lightweight, flexibility, and processability. This review summarizes the research progress in triboelectric yarns. It starts with a systematic discussion of the working mechanism and manufacturing materials of triboelectric yarns. Subsequently, we discuss the four major methods of constructing triboelectric yarns including twisting/wrapping, coating, electrospinning, and other/composite methods. In particular, details about the energy harvesting performance, the triboelectric yarns' physical properties, and weaving/knitting capability are given. Finally, comments and perspectives are provided for the future design of high-performance triboelectric yarns.
