“…The sensor displays a maximum GF of −1.7 in the strain range of 15% during x-direction stretching and −26 within an 8% strain range with y-direction stretching. Ravinder Reddy K et al [ 96 ] use the same method to prepare the RGO polyester knitted elastic band (RGOPEB) strain sensor, which exhibits excellent performance including great sensitivity, a low detection limit, and good durability and stability. Cai et al [ 97 ] manufacture high sensitive strain sensing fabrics (FSSFs) with washability (resistance increased from ~112 kΩ/m 2 to ~154 kΩ/m 2 after 8 washing cycles).…”

Graphene-based textile strain sensors were reviewed in terms of their preparation methods, performance, and applications with particular attention on its forming method, the key properties (sensitivity, stability, sensing range and response time), and comparisons. Staple fiber strain sensors, staple and filament strain sensors, nonwoven fabric strain sensors, woven fabric strain sensors and knitted fabric strain sensors were summarized, respectively. (i) In general, graphene-based textile strain sensors can be obtained in two ways. One method is to prepare conductive textiles through spinning and weaving techniques, and the graphene worked as conductive filler. The other method is to deposit graphene-based materials on the surface of textiles, the graphene served as conductive coatings and colorants. (ii) The gauge factor (GF) value of sensor refers to its mechanical and electromechanical properties, which are the key evaluation indicators. We found the absolute value of GF of graphene-based textile strain sensor could be roughly divided into two trends according to its structural changes. Firstly, in the recoverable deformation stage, GF usually decreased with the increase of strain. Secondly, in the unrecoverable deformation stage, GF usually increased with the increase of strain. (iii) The main challenge of graphene-based textile strain sensors was that their application capacity received limited studies. Most of current studies only discussed washability, seldomly involving the impact of other environmental factors, including friction, PH, etc. Based on these developments, this work was done to provide some merit to references and guidelines for the progress of future research on flexible and wearable electronics.

Wearable technology has been evolving from rigid electronic accessories toward soft and flexible electronic components that can be seamlessly integrated into a garment. [1] This new generation of wearables requires electronic textiles (E-textiles) to have enhanced comfort for the wearer with high flexibility and conformability which is similar to the properties of conventional textiles. E-textiles have received considerable interest due to their potential applicability in a variety of wearable clothing, such as sportswear, [2] military uniforms, [3] firefighting garments, [4] health-care products, [5] and tracking systems. [6] The functions of electronic devices composed of E-textiles include sensors for monitoring physical parameters (e.g., temperature, [7] humidity, [8] strain, [9] and pressure [10]) and biological signals (e.g., heart rate, [11] respiration, [12] and the composition of sweat [13]); energy storage [14] and energy harvesting devices; [15] and signal transmission and communication systems. [16] To achieve textiles with electronic functionalities, it is crucial to introduce electrically conductive materials such as metals, although the introduction of semiconducting and insulating materials may also be necessary depending on the intended application. Recently, aluminum, one of the metal conductors, has shown the potential to replace expensive metals such as silver and gold in E-textile applications. [17] There are two main approaches for patterning conductive materials on textile substrates, namely, utilizing conductive inks or suspensions (e.g., screen printing, inkjet printing, dispensing, and spray coating) [18] and using conductive yarns (e.g., embroidery, knitting, Jacquard weaving, and stitching). [19] Embroidery is one of the most popular methods for applying conductive yarns to a fabric substrate. Using this additive process, conductive lines or areas can be patterned on conventional nonconducting fabrics such as cotton and polyester, which is an advantage over knitting and Jacquard weaving. The embroidery process, however, is time-consuming and depending on the yarn thickness, there may be difficulties in obtaining a high resolution when filling in large areas. Furthermore, the embroidered area often has a thick and rigid structure, which degrades the flexibility and stretchability of the final wearable device. Direct-printing processes, such as inkjet printing and dispensing, utilizing conductive inks or suspensions have also been intensively studied for the fabrication of conductive patterns because they make it possible to produce various patterns with extremely high resolution. However, direct printing has a similar disadvantage to embroidery as the rates of these processes rely

Textile electronics addresses fibers or fiber assemblies with electronic functions to generate, transmit, modulate, and detect electrons. Interactive textile electronic devices may provide suitable platforms for virtual reality (VR)/augmented reality (AR) applications because of their excellent performance and unique immersive features such as lightweight, handiness, flexibility, comfort, and low strain even under high deformations. This paper presents a systematic review of the literature on the state‐of‐the‐art of interactive devices, fabrication technologies, system integration, promising applications, and challenges involved in textile‐based VR/AR systems.
