“…The average number of cycles run in this cluster is 19, but there is a large variation in the number of conducted test cycles (see Table 2): Martinez-Estrada et al wash their test samples only twice, while Liang et al test for three cycles. 26,29 In contrast, five sources have conducted 50 wash cycles, four of which stem from the University of Lille. 12,30,38,40 Gerhold does not run a predetermined number of cycles, but instead stops testing at the first occurrence of detached components, after 16 cycles.…”

Washability is seen as one of the main obstacles that stands in the way of a wider market success of e-textile products. So far, there are no standardized methods for wash testing of e-textiles and no protocols to comparably assess the washability of tested products. Thus, different e-textiles that are deemed equally washable by their developers might present with very different ranges of reliability after repeated washing. This paper presents research into current test practices in the absence of e-textile-specific standards. Different testing methods are compared and evaluated and the need for standardized testing, giving e-textile developers the tools to comparably communicate and evaluate their products’ washability, is emphasized.

“…Different sensors need to be combined under one system to complete the task; this thought gives rise to the concept of developing textile-based sensors and electrodes. The production methods include but are not limited to knitting, [17] weaving, [18] coating, [19] embroidery, [20] and sewing. [21] Smart clothing is not just about sensing, but once they sense a change, they can keep us warm or cool according to the environment, [22][23][24] help prevent muscle drag while running, [25] can be antimicrobial, or have sweat-wicking properties.…”

Textronics contribute a significant part of Internet‐of‐Things (IoT), which empowers added functionalities by connecting smart clothing in a secure way for diverse applications. For the development of flexible and stretchable textile‐based electronics, a conductive material (yarn, fabric, etc.) must be used, and fabrication techniques play a vital role that significantly influences electronic textiles’ properties. Textile‐based sensors, electrodes, and other devices seem to be the favorite choice for continuous wearable monitoring due to their low cost, flexibility, and ease of embedding. Integrating smart capabilities into textiles provides substantial benefits in the fields of healthcare, sports, automobile, and military. These developments have a profound influence on the Fourth Industrial Revolution (4IR). This Review presents an in‐depth study of the current state of the art in the area of textile‐based electronics. The design, development, and evaluation techniques are discussed. Certain limitations and research gaps are also addressed regarding this emerging field. Critically, this Review is more application focused and indicates how the recent developments in electronic textiles will soon impact our lives. As these areas have typically been neglected in previous reviews, additional knowledge to the existing literature is provided by bridging the gap between the academic research and commercialization of wearable Textronics.

“…When graphene‐based sensors are fabricated with woven fabrics, they generally exhibit dimensional stability, but exhibit limited elastic recovery during human motions, making it difficult to adapt to the human body 27–29 . Knitted structures are more suitable in creating flexible structures which closely fit the human body without restricting motions and therefore are more suitable as strain sensor applications for collecting data close to the body with the integration method remaining hidden 14,30,31 …”

Flexible strain sensors have attracted considerable attention due to their applications in wearable monitoring fields such as human-computer interaction systems, athletic training, and health systems. Textiles are a desired substrate for fabricating wearable flexible sensors due to their light weight, comfort, and flexibility. However, the compatibility between textiles and conductive materials still faces critical challenges, especially for wearable sensors to achieve high sensitivity and a wide sensing range simultaneously with long-term monitoring stability, reliability, and wearing comfort. In this study, we propose a graphene-based TPU/textile composite sensor that can be produced using small-scale manufacturing techniques, using laser cutting combined with film coating and thermal transfer processes and further explore its mechanical, electrical, and sensing properties. Since the human body exhibits different magnitudes of motion and fabric sensors integrated into clothing would face multiple challenges in real world usage e.g. repetitive wear, sweat and sunlight exposure, we performed sensitivity, reliability and durability tests to further evaluate real world usage of the fabric sensors. The developed composite sensor exhibits a high sensitivity (GF = 498), wide sensing range (0%-293%), excellent reliability and stability which only shows 5% deviation after 10,000 cycles of stretching under 5% strain. In addition, the graphene-based textile composite sensor thermalised by TPU film can also maintain high stability after long-term UV irradiation and multiple washing cycles. When integrated into various wearable devices, our composite sensor can detect a wide range of human body motions accurately, as well as subtle physiological signals, exhibiting great potential in incorporating into wearable monitoring devices.
