“…Due to low cost, high efficiency, and mature technology, it is very possible to realize the large‐scale production of this energy harvesting fiber. Printing as one of effective methods for mass production has also been adopted to prepare a SE‐mode single fiber‐based TENG by using CNTs as a conductive core and silk fibroin as a dielectric sheath . Unfortunately, stretchability is absent in the above SE mode single fiber‐based TENGs due to the existence of straight core fiber.…”

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...

“…Recently Zhang and co‐workers reported direct printing of core‐sheath fiber‐based smart patterns for energy/management E‐textile, using CNTs as a conductive core and silk fibroin as a dielectric sheath. [ 175 ] Chen and co‐workers demonstrated that it was possible to fabricate the asymmetric GO/polyaniline (PANi) microsupercapacitors using 3D extrusion printing which exhibits improvement in the voltage window, energy density, power density, and cycling stability compared with the symmetric microsupercapacitors. [ 176 ] Photodetectors consisting of semiconducting polymer poly(3‐hexylthiophene) (P3HT):[6,6]‐phenyl C61‐butyric acid methyl ester (PCBM) blend were printed via a layer‐by‐layer deposition process.…”

3D printing is a rapidly growing technology that has an enormous potential to impact a wide range of industries such as engineering, art, education, medicine, and aerospace. The flexibility in design provided by this technique offers many opportunities for manufacturing sophisticated 3D devices. The most widely utilized method is an extrusion‐based solid‐freeform fabrication approach, which is an extremely attractive additive manufacturing technology in both academic and industrial research communities. This method is versatile, with the ability to print a range of dimensions, multimaterial, and multifunctional 3D structures. It is also a very affordable technique in prototyping. However, the lack of variety in printable polymers with advanced material properties becomes the main bottleneck in further development of this technology. Herein, a comprehensive review is provided, focusing on material design strategies to achieve or enhance the 3D printability of a range of polymers including thermoplastics, thermosets, hydrogels, and other polymers by extrusion techniques. Moreover, diverse advanced properties exhibited by such printed polymers, such as mechanical strength, conductance, self‐healing, as well as other integrated properties are highlighted. Lastly, the stimuli responsiveness of the 3D printed polymeric materials including shape morphing, degradability, and color changing is also discussed.

“…Alternative techniques have been developed to fabricate conductive textiles, such as integrating metal filaments with yarns, coating fibers with a thin layer of conductive materials (metal nanoparticles/nanowires, carbon nanotubes, graphene, etc. ), or direct patterning of conducting polymers, and inkjet/stencil/screen/nozzle printing of conductive materials onto textiles ( Figure ) . The inclusion of metal wires in the yarns would increase the stiffness of the textiles and thereby decrease the wear comfort.…”

Flexible and stretchable electronics are attracting tremendous attention for their enormous future potential in wearable technologies. Flexible and stretchable sensors and conductors are the key components of wearable devices for potential applications such as human motion detection, human health monitoring, and human–machine interfaces. One critical requirement for them is to show high level of wearability (bendability and stretchability) and meanwhile to retain their functionality and reliability under large mechanical deformation. To this end, a wide range of materials and structural designs are developed to construct these sensors and conductors. Here, the recent advances in the development of new piezoresistive materials and microstructural motifs that endow electronics with flexibility and stretchability are summarized. Challenges and future opportunities are discussed in terms of the multimodal and multidirectional sensing capabilities, the trade‐off between sensitivity/conductivity and stretchability, multifunctionality, linearity (multiple linear region phenomenon), and integration with flexible power and communication devices.
