“…The breathability of the fabric compared with other common wear fabrics is displayed in Figure e. The air breathability of the fabric is 171.0 mm/s, which is similar to the commercial cotton T-shirt fabric (170.8 mm/s) and much higher than that of the commercial denim fabric (24.75 mm/s) . The moisture permeability of the fabric is 3834 g/m 2 ·24 h, which is similar to that of cotton fabrics (3819 g/m 2 ·24 h) but higher than that of denim fabric (3589 g/m 2 ·24 h) .…”

Body temperature is an important indicator of human health. The traditional mercury and medical electronic thermometers have a slow response (≥1 min) and can not be worn for long to achieve continuous temperature monitoring due to their rigidity. In this work, we prepared a skin-core structure polyurethane (PU)/graphene encapsulated poly(3,4-ethylenedioxythiophene)–poly(styrenesulfonate) (PEDOT:PSS) temperature-sensitive fiber in one step by combining wet spinning technology with impregnation technology. The composite fiber has high sensitivity (−1.72%/°C), super-resolution (0.1 °C), fast time response (17 s), antisweat interference, and high linearity (R 2 = 0.98) in the temperature sensing range of 30–50 °C. The fiber is strong enough to be braided into the temperature-sensitive fabric with commercial cotton yarns. The fabric with good comfort and durability can be arranged in the armpit position of the cloth to realize real-time body temperature monitoring without interruption during daily activities. Through Bluetooth wireless transmission, body temperature can be monitored in real-time and displayed on mobile phones to the parents or guardians. Overall, the fiber-based temperature sensor will significantly improve the practical applications of wearable temperature sensors in intelligent medical treatment due to its sensing stability, comfort, and durability.

“…The fundamental working modes of TENGs can be divided into four categories: vertical contact-separation mode, lateral sliding mode, single-electrode mode, and free-standing mode [ 35 , 36 , 37 , 38 ]. Inspired by these, researchers have invented many kinds of fabric-based devices [ 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. Some of these devices are based on woven structures [ 47 , 48 , 49 , 50 , 51 ] and others on knitted structures [ 52 , 53 ].…”

Research in the field of wearable triboelectric generators is increasing, and pioneering research into real applications of this technology is a growing need in both scientific and industry research. In addition to the two key characteristics of wearable triboelectric generators of flexibility and generating friction, features such as softness, breathability, washability, and wear resistance have also attracted a lot of attention from the research community. This paper reviews wearable triboelectric generators that are used in human clothing for energy conversion. The study focuses on analyzing fabric structure and examining the integration method of flexible generators and common fibers/yarns/textiles. Compared to the knitting method, the woven method has fewer restrictions on the flexibility and thickness of the yarn. Remaining challenges and perspectives are also investigated to suggest how to bring fully generated clothing to practical applications in the near future.

“…A popular method for obtaining this structure involves conjugate electrospinning to cover the surface of the core fiber with an outer nanofibrous film. This kind of core–sheath yarn is more stable than that obtained by surface coating. , Chen et al designed a three-tier structure nanofiber yarn (NMSY) applied for self-powered biomechanical sensors via conjugate electrospinning and ring spinning techniques. The NMSY possesses the triboelectric functionality, which is composed of a pure copper yarn (PCY) as the core, ZnO-doped PA11 as the middle layer, and PET nanofibers as the outermost layer.…”

Electrospun micro/nanofibers have gained popularity recently for flexible biomechanical sensors because of their advantages of lightness, compatibility, breathability, mechanical deformability, and function integrability, etc., offering them unprecedented sensitivities and versatilities. With increasing advances in the digital era, existing electrospun flexible sensors are not capable of catering to the demands of multiscenario applications including wearable electronics, interactive interfaces, and real-time continuous health monitoring. To ease and expedite their developments, we thoroughly reviewed their latest progress regarding design, preparation, and optimization. First, a brief overview of the design approaches of electrospun flexible biomechanical sensors based on the working mechanism is highlighted. Then, two kinds of preparation strategies including direct electrospinning and post-treatment-assisted electrospinning are discussed in detail. Further, four means for optimizing the performance and endowing multifunctions to electrospun flexible biomechanical sensors are demonstrated in terms of processing. Accordingly, the challenges and the potential solutions related to this topic are addressed, providing a future direction for the next generation of electrospun flexible biomechanical sensors.
