“…In other words, e-textiles can be electronically integrated textiles built with different responsive electronic components to sense, react, and adapt themselves in a given circumstance [123]. In a wearable e-garment, different sensors [124,125] and actuators [126,127] that are necessarily made of textiles are embedded and connected to a flexible power supply (fibrous supercapacitor [128,129], solar cell [130], nanogenerator [131,132], etc.) data processor, along with an external communication platform (Wi-Fi) for the acquired data to be further processed and monitored remotely.…”

Flexible electronic textiles are the future of wearable technology with a diverse application potential inspired by the Internet of Things (IoT) to improve all aspects of wearer life by replacing traditional bulky, rigid, and uncomfortable wearable electronics. The inherently prominent characteristics exhibited by textile substrates make them ideal candidates for designing user-friendly wearable electronic textiles for high-end variant applications. Textile substrates (fiber, yarn, fabric, and garment) combined with nanostructured electroactive materials provide a universal pathway for the researcher to construct advanced wearable electronics compatible with the human body and other circumstances. However, e-textiles are found to be vulnerable to physical deformation induced during repeated wash and wear. Thus, e-textiles need to be robust enough to withstand such challenges involved in designing a reliable product and require more attention for substantial advancement in stability and washability. As a step toward reliable devices, we present this comprehensive review of the state-of-the-art advances in substrate geometries, modification, fabrication, and standardized washing strategies to predict a roadmap toward sustainability. Furthermore, current challenges, opportunities, and future aspects of durable e-textiles development are envisioned to provide a conclusive pathway for researchers to conduct advanced studies.

“…The ADN hydrogel had the advantages of high sensitivity, fast response, wide sensing range, and good stability. Therefore, the wearable strain sensor based on the ADN hydrogel had a broad application prospect in human motion detection (Wang S. L. et al, 2022;Li et al, 2022). Herein, the ADN 1.5 hydrogel was made into a wearable strain sensor, which was attached to the volunteer's skin to monitor the movements of the human body from tiny deformations to large-scale motions in realtime.…”

Hydrogel-based flexible electronic devices are essential in future healthcare and biomedical applications, such as human motion monitoring, advanced diagnostics, physiotherapy, etc. As a satisfactory flexible electronic material, the hydrogel should be conductive, ductile, self-healing, and adhesive. Herein, we demonstrated a unique design of mechanically resilient and conductive hydrogel with double network structure. The Ca2+ crosslinked alginate as the first dense network and the ionic pair crosslinked polyzwitterion as the second loose network. With the synthetic effect of these two networks, this hydrogel showed excellent mechanical properties, such as superior stretchability (1,375%) and high toughness (0.57 MJ/m3). At the same time, the abundant ionic groups of the polyzwitterion network endowed our hydrogel with excellent conductivity (0.25 S/m). Moreover, due to the dynamic property of these two networks, our hydrogel also performed good self-healing performance. Besides, our experimental results indicated that this hydrogel also had high optical transmittance (92.2%) and adhesive characteristics. Based on these outstanding properties, we further explored the utilization of this hydrogel as a flexible wearable strain sensor. The data strongly proved its enduring accuracy and sensitivity to detect human motions, including large joint flexion (such as finger, elbow, and knee), foot planter pressure measurement, and local muscle movement (such as eyebrow and mouth). Therefore, we believed that this hydrogel had great potential applications in wearable health monitoring, intelligent robot, human-machine interface, and other related fields.

“…Recently, flexible electronics have been attracting tremendous attention because of their merits, such as high compatibility, conformal contact with human skin, and easy integration on diverse IoT platforms. However, toward the rich application scenarios, for instance, personalized medicine [ 1 , 2 ], chemical sensors [ 3 ], personal motion monitoring [ 4 ], personalized electronic device customization [ 5 ], and so on, the true potential of IoT can only be realized if they are made self-sustainable, either by reducing the power consumption of the IoT through ultra-low-power-consumption circuits and low-voltage operation, or combining them with energy-harvesting technologies and making more energy available, or in most cases, hand in hand [ 6 , 7 , 8 ]. Meanwhile, as an emerging and ever-growing technological field, another challenging issue is to make flexible electronic materials as well as integrated power sources both durable and powerful in strained states, especially for applications such as skin-like electronics, implantable biodegradable devices [ 9 , 10 , 11 ], and bioinspired soft robotics [ 12 , 13 , 14 , 15 , 16 ].…”

There is an increasing need for structural flexibility in self-powered wearable electronics and other Internet of Things (IoT), where adaptable triboelectric nanogenerators (TENGs) play a key role in realizing the true potential of IoT by endowing the latter with self-sustainability. Thus, in this review, the topic was restricted to the adaptive design of TENGs with structural flexibility that aims to promote the sustainable operation of various smart electronics. This review begins with an emphatical discussion of the concept of flexible electronics and TENGs, and continues with the introduction of TENG-based self-powered intelligent systems while placing the emphasis on self-powered flexible intelligent devices. Self-powered healthcare sensors, e-skins, and other intelligent wearable electronics with enhanced intelligence and efficiency in practical applications due to the integration with TENGs are illustrated, along with an emphasis on the design strategy of structural flexibility of TENGs and the associated integration schemes. This review aims to cover recent achievements in the field of self-powered systems, and provides information on how flexibility or adaptability in TENGs can be adopted, their types, and why they are required in promoting advanced IoT applications with sustainability and intelligence algorithms.
