“…The PPy dip-coated cotton fabric used for the construction of a strain sensor is shown in Figure 7. Furthermore, Mule et al used this technique to fabricate a conductive and robust PPy-coated cotton triboelectric nanogenerators (TENGs) device which was flexible and wearable [104]. The device efficiently converts mechanical energy into electricity while making a continuous touch-release with counter friction objects like human skin, i.e., tibo-friction layers.…”

In the last three decades, the development of new kinds of textiles, so-called smart and interactive textiles, has continued unabated. Smart textile materials and their applications are set to drastically boom as the demand for these textiles has been increasing by the emergence of new fibers, new fabrics, and innovative processing technologies. Moreover, people are eagerly demanding washable, flexible, lightweight, and robust e-textiles. These features depend on the properties of the starting material, the post-treatment, and the integration techniques. In this work, a comprehensive review has been conducted on the integration techniques of conductive materials in and onto a textile structure. The review showed that an e-textile can be developed by applying a conductive component on the surface of a textile substrate via plating, printing, coating, and other surface techniques, or by producing a textile substrate from metals and inherently conductive polymers via the creation of fibers and construction of yarns and fabrics with these. In addition, conductive filament fibers or yarns can be also integrated into conventional textile substrates during the fabrication like braiding, weaving, and knitting or as a post-fabrication of the textile fabric via embroidering. Additionally, layer-by-layer 3D printing of the entire smart textile components is possible, and the concept of 4D could play a significant role in advancing the status of smart textiles to a new level.

“…[ 99–105 ] The fundamental working modes of TENGs can be divided into four categories, including vertical contact‐separation mode, [ 106–110 ] lateral sliding mode, [ 111–115 ] single‐electrode mode, [ 116–119 ] and freestanding triboelectric‐layer mode. [ 120,121 ] Thanks to high energy output and relatively stable energy conversion efficiency, TENGs were demonstrated to drive a wide range of small electronics, including watches, [ 122–125 ] alarm bells, [ 126,127 ] mobile phones, [ 128,129 ] light emitting diodes (LEDs), [ 130–133 ] pedometers, [ 134 ] and a wide variety of sensors.

With the rapid development of the Internet of Things (IoT) and the ongoing Fourth Industrial Revolution, the effective conversion of wasted ambient mechanical energy from the environment to generate electricity is regarded as one of the most pivotal technologies for powering widely distributed electronics in the era of the Internet of Things. Although the triboelectric nanogenerator (TENG), based on the coupling effect of contact electrification and electrostatic induction, has recently undergone a tremendous evolution with the development of various features such as flexibility, conformability, and user‐friendliness, further improvement of the output performance is still required for usage toward practical applications for the next‐generation of IoT devices. In this review article, surface nanostructure modification methods for high‐performance triboelectric nanogenerators are systematically summarized. The field is deeply reviewed, with the methods classified into four categories: templating method, appending method, etching method, and crumpling method. Finally, an in‐depth discussion of the existing challenges and the direction of future efforts for enhancing TENG output performance are clearly stated, which can contribute to promoting further development of the field.

Fiber that has been known for thousands of years for textile engineering, is a kind of thin 1D material with large length-diameter ratio and softness. Fiber can be further processed into 1D or 3D yarns and 2D or 3D fabrics and can be subjected to wellestablished textile manufacturing techniques, such as dyeing, twisting, sewing, knitting, weaving, braiding, etc. [1] As commercially available material, fabric has been widely used for clothing, bedding, or furniture. Such wide-adoption demonstrates fabrics/textiles to be important and adaptable as daily useable material due to their merits of protection, breathability, comfort, and durability. [2] In recent years, novel smart responsive functions are desirable to be implemented on fibers and fabrics for seamless integrations of actuators, sensors, power sources, etc., to realize the robotic fibers/fabric-based manipulators and human-robot interfaces. These emerging responsive fibers/ fabrics are desirable to offer programmable functions, actuations, perception and capable of building an intuitive and dynamic collaborative scenarios with human, promising in enabling applications such as remote operation, human motion assistance, human perception, health monitoring and biomedical detection and therapy. [3][4][5] It is an attractive concept that the future human-robot interfaces could be embodied in familiar forms for humans such as textiles or clothes. Compared with the polymeric and elastomeric soft robotics, [6][7][8][9] fibers and fabrics are advantageous in applications of soft robotics and wearables for human. The devices could be programmable to have accurate designs in configuration and high performance by traditional manufacturing processes of textile, applying twist to transform fibers into coils, yarns with hierarchical structures, which could be further fabricated into fabrics or textiles by sewing, weaving, knitting, etc., techniques (Figure 1), guaranteeing good wearability, skin affinity, washability, and durability, which are intriguing and necessary for friendly robotics interactions with human.Soft robotics include three main components of actuators, sensors, and control modules with power sources. [10,11] Of which, actuators, sensors and power sources all could be designed in the form of fibers or fabrics, rendering facile assembly, and integration by interlocking. [12] Common actuations can be Soft robotics inspired by the movement of living organisms, with excellent adaptability and accuracy for accomplishing tasks, are highly desirable for efficient operations and safe interactions with human. With the emerging wearable electronics, higher tactility and skin affinity are pursued for safe and user-friendly human-robot interactions. Fabrics interlocked by fibers perform traditional static functions such as warming, protection, and fashion. Recently, dynamic fibers and fabrics are favorable to deliver active stimulus responses such as sensing and actuating abilities for soft-robots and wearables. First, the responsive mechanisms of fiber/fabric actu...
