“…Different from the above methods such as attaching, coating, depositing and sputtering, interdigitated fabric structure can be directly obtained from textile forming techniques, which not only maintains the integrity and aesthetic perception of fabrics, but also simplifies the whole preparation processes. As shown in Figure e, an FT mode fabric‐based TENG with knitted structure was designed by knitting cotton fibers alternatively between two Ag‐coated nylon fabrics at a fixed interval . Its power generation was achieved by in‐plane sliding with an upper PTFE fabric.…”

fields is breaking out, such as the Internet of Things (IoTs), big data, humanoid robotics, and artificial intelligence (AI). Nowadays, the rapid advancement of these functional electronic devices is transforming the way people communicate with each other and with their surroundings, which has integrated our world into an intelligent information network. Owing to that no electronics works without electricity, the processes of human informatization and intelligence depend on broad energy supplies and powerful power supports. In other words, electric power can be regarded as the flowing blood that keeps every components of the current society running normally and healthily. However, with the rapid consumption of conventional fossil fuels as well as the growing voice of environmental protection, the current energy structure and its supply status are facing unprecedented challenges. On the one hand, the overwhelming energy crisis and ecological deterioration have become huge bottlenecks restricting socioeconomic development.[1] Some serious situations may even worsen to the root of interstate interest conflicts or the disaster that threatens the survival of mankind. In this case, the transform of energy structure from scarce, pollution-prone, and irreproducible mineral resources to abundant, environmentally friendly, and renewable green energies is desperately required. On the other hand, the traditional centralized, immobile, and ordered energy supply patterns based on power plants are incompatible with the present development of functional electronics associated with individual person, which follows a general trend of miniaturization, portability, and low power. As the information age is coming, billions of things must be connected with sensors for various measurements, perceptions, controls, and data transmissions. [2] These mobile, human-oriented, randomly and massively distributed sensing networks also require the corresponding matched power supply system. Therefore, it turns out that the unreasonable energy structures as well as the mismatched supply pattern lead to the current development dilemma.Portable power supplies and self-powered systems are the most promising solutions for the above straits. For wearable power sources, one of the compromises is to choose small-size Integration of advanced nanogenerator technology with conventional textile processes fosters the emergence of textile-based nanogenerators (NGs), which will inevitably promote the rapid development and widespread applications of next-generation wearable electronics and multifaceted artificial intelligence systems. NGs endow smart textiles with mechanical energy harvesting and multifunctional self-powered sensing capabilities, while textiles provide a versatile flexible design carrier and extensive wearable application platform for their development. However, due to the lack of an effective interactive platform and communication channel between researchers specializing in NGs and those good at textiles, it is rather difficult to achieve fiber...

“…Fiber‐based textile electric devices have been attracting great interest, owing to the huge demand for wearable electronics in recent years . For real‐life applications, one crucial factor determining the wearable device's viability is the washability . This property needs electrode materials and a conductive network that is more strongly clad on the substrate.…”

body is actually a tremendous storehouse of energy that is generated from body heat and motion. [15][16][17][18][19] Power generation from breathing, heating, blood transport, arm motion, typing, and walking could reach to over 100 W for a 68 kg adult's daily activities (Figure 1). [20] Thus, converting 1% of power from the human body may be enough to support the work of most portable electronics.In the past two decades, researchers have developed several energy conversion devices based on piezoelectricity, electrostaticity, triboelectricity, or thermoelectricity that can directly harvest the mechanical or thermal energy and convert it into electric energy (these conversion devices are so-called nanogenerators (NGs)). [21][22][23][24][25] The first nanogenerator (NG) based on ZnO was invented by Prof. Wang in 2006; after that, various NGs were developed to harvest the mechanical or thermal energy with the output performance increasing gradually. [26] These NGs are easy-to-construct flexible devices since most materials for these devices are polymers and nanomaterials. Generally, the flexible devices assembled by film materials can be stretchable and bendable in one direction. But their lack of air-permeability, poor 3D deformation, and low damage tolerance limit their application, especially for wearable electronics. Therefore, fiberbased energy conversion devices have been designed. [27] These fiber-based devices can also be knitted to yarn or fabric in the clothing system to build up a large area electronic system. [28,29] The energy generation and internal charging can be realized by means of a self-powered system that harvests the energy from natural sources around the human body to sustain the wearable electronics. [30][31][32] The search for functional materials that possess good conversion efficiency, as well as great mechanical and environmental stability, combined with a novel device design might push these devices to meet the requirement of a practical application. In the past decade, numerous contributions have been offered to improve the performance of fiber-based energy conversion devices (FBECD) and extend its application. This review specifically summarizes FBECD with different energy conversion mechanisms including piezoelectricity, electrostaticity, triboelectricity, and thermoelectricity in recent processes (Figure 2). The functional materials, fiber fabrication techniques, and device design strategies for different classes of FBECDs are covered in the article. We also introduce an overview of the fiber-based self-powered system and sensors and Following the rapid development of lightweight and flexible smart electronic products, providing energy for these electronics has become a hot research topic. The human body produces considerable mechanical and thermal energy during daily activities, which could be used to power most wearable electronics. In this context, fiber-based energy conversion devices (FBECD) are proposed as candidates for effective conversion of human-body energy into electricity...

“…Tremendous efforts have been made to fabricate various TENGs based on fabrics or textiles, including improving the triboelectric performance, operability, and washability of devices. In general, there are two routes to achieve the textile TENGs, the first one is fabricating the TENGs based on yarns, threads, and belts, followed by weaving those units into textile devices to improve the applicability [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85]. The second way is realizing TENGs by in situ functionalization directly on the off-the-shelf textiles that were woven by synthetic or natural fibers/yarns [86][87][88][89][90][91][92][93][94][95][96][97][98][99][100].…”

Textile has been known for thousands of years for its ease of use, comfort, and wear resistance, which resulted in a wide range of applications in garments and industry. More recently, textile emerges as a promising substrate for self-powered wearable power sources that are desired in wearable electronics. Important progress has been attained in the exploitation of wearable triboelectric nanogenerators (TENGs) in shapes of fiber, yarn, and textile. Along with the effective integration of other devices such as supercapacitor, lithium battery, and solar cell, their feasibility for realizing self-charging wearable systems has been proven. In this review, according to the manufacturing process of traditional textiles starting from fibers, twisting into yarns, and weaving into textiles, we summarize the progress on wearable TENGs in shapes of fiber, yarn, and textile. We explicitly discuss the design strategies, configurations, working mechanism, performances, and compare the merits of each type of TENGs. Finally, we present the perspectives, existing challenges and possible routes for future design and development of triboelectric textiles.
