“…With the purpose of fully grasping the development trend of TENGs in the two indicators in recent years, the peak power density and pressure sensitivity of TENGs with curved fiber structures are first summarized with the focus on comparing with planar membrane structures.

of textile materials from ancient times to the present, and then to the future is shown in Figure 1, indicating that typical textile materials that can highlight the characteristics of the times have experienced the transformation from natural fiber, artificial/synthetic fiber, reinforced fiber, functional fiber, conductive fiber, and then to smart fiber. Accordingly, the primary purposes or service demands of textile materials have also changed imperceptibly from the aspects of covering, warmth preservation, protection, beauty, security, comfort, health, interaction, and intelligence. On these grounds, it can be found that with the advances of Internetof-Things and artificial intelligences, textile materials are no longer limited to the traditional functions of protection, warm-keeping, and aesthetic, but should be given more smart or intelligent attributes, such as energy harvesting, [1][2][3] energy storage, [4,5] autonomous response, [6,7] information interaction, [8,9] data transmission, [10,11] light emitting, [12,13] color changing, [14] shape memory, [15] thermal regulation, [16,17] selfhealing, [18a] self-adaption, [19] etc. In addition, considering that human oriented wearable electronics will be highly integrated and miniaturized, completely safe and comfortable, and fully portable in the future, it is also expected to design various functional electronics directly into textile structures, such as fibers, yarns or fabrics. [20,21] At present, a variety of functional attributes have been well integrated with textile materials, mainly including energy, [3,4,12,22] sensing, [8,10,23,24] comfort, [16,25a,26,27] and protection, [19,[28][29][30] which endows this kind of traditional necessity of life with new development vitality (Figure 2). In particular, through the seamless combination of electrical functionalities and textile elements, a new type of textiles, namely smart textiles, have been developed, which can perceive, react and adapt to environmental stimuli, including machinery, magnetism, heat, electricity, light, chemistry, biology, and others. [31][32][33][34][35] It can be predicted that the realization of highperformance electrical function and comfortable to wear is the unremitting pursuit goal of the next generation of smart textiles.It is noteworthy that the effective operation of most additional functions in smart textiles depends on sustained and stable energy sources. In other words, we need reliable, compact but high-performance electricity supply systems to power emergingThe seamless integration of emerging triboelectric nanogenerator (TENG) technology with traditional wearable textile materials has given birth to the next-generation smart textiles, i.e., textile TENGs, which will play a vital role in the era of Internet of Things and artificial intelligences. However, low output power and inferior sensing ability have largely limited the development of textile TENGs. Among various approaches to improve the output and sensing performance, such as material modification, structural des...

“…The density can reach 263.36 mW/m 2 at a percussion frequency of 3 Hz, which is several times that of traditional 2D textile TENG. There are more and more applications in T-TENG based on yarn structure or core-shell structure [23,26,27,87], usually each yarn has a separate electrode and triboelectric material, so it can be used as a TENG alone for energy collection, TENG fabric can also be obtained by weaving.…”

In recent years, wearable electronic devices have made considerable progress thanks to the rapid development of the Internet of Things. However, even though some of them have preliminarily achieved miniaturization and wearability, the drawbacks of frequent charging and physical rigidity of conventional lithium batteries, which are currently the most commonly used power source of wearable electronic devices, have become technical bottlenecks that need to be broken through urgently. In order to address the above challenges, the technology based on triboelectric effect, i.e., triboelectric nanogenerator (TENG), is proposed to harvest energy from ambient environment and considered as one of the most promising methods to integrate with functional electronic devices to form wearable self-powered microsystems. Benefited from excellent flexibility, high output performance, no materials limitation, and a quantitative relationship between environmental stimulation inputs and corresponding electrical outputs, TENGs present great advantages in wearable energy harvesting, active sensing, and driving actuators. Furthermore, combined with the superiorities of TENGs and fabrics, textile-based TENGs (T-TENGs) possess remarkable breathability and better non-planar surface adaptability, which are more conducive to the integrated wearable electronic devices and attract considerable attention. Herein, for the purpose of advancing the development of wearable electronic devices, this article reviews the recent development in materials for the construction of T-TENGs and methods for the enhancement of electrical output performance. More importantly, this article mainly focuses on the recent representative work, in which T-TENGs-based active sensors, T-TENGs-based self-driven actuators, and T-TENGs-based self-powered microsystems are studied. In addition, this paper summarizes the critical challenges and future opportunities of T-TENG-based wearable integrated microsystems.

“…Although textile TENGs have been widely used in the field of flexible sensing, it ignores the key issue of smart fabrics preparation process, which makes it limited in scale preparation and application to different degrees 30 . For example, most triboelectric fibers are usually prepared by coating a dielectric material on a conductive material 31,32 . The preparation process is complicated, costly, long preparation time, and inhomogeneous 33,34 .…”

Flexible and wearable energy harvesting devices and multifunctional sensors have been widely reported, but challenges in the large‐scale manufacturing process still exist. This work reports a large‐scale fabrication method of core‐shell triboelectric braided fibers that exhibit stable structure and strong tensile strength, which can be further integrated into power textiles with different fabric structures, such as weaving and knitting, with the purpose of biomechanical energy harvesting or plantar pressure monitoring. The triboelectric braided fibers integrating on the knitting power textiles exhibit good pressure sensitivity and fatigue resistance, which is combined with traditional socks to measure the pressure distribution of the plantar in different positions. The weaving power textiles exhibit high electrical output, which can be used for biomechanical energy harvesting and can easily light up 116 commercial LEDs. This large‐scale preparation approach provides more possibilities for power textiles applications in self‐powered wearable electronics and human–computer interfacing.
