Smart electronic textiles are gaining a lot of importance in the field of flexible and wearable devices because of their lightweight, flexibility, deformability, and facile interaction with human skin. Herein, a simple, inexpensive, and scalable dip‐dry‐reduce approach method is reported to fabricate a flexible strain sensor using polyester knitted elastic band (PEB) as the platform material which is coated with reduced graphene oxide, and its potential applications are demonstrated in detecting both the subtle and large‐scale deformations of the human body. PEB is made by knitting polyester yarn around a series of inner rubber cores, which makes it very versatile, lightweight, and shrink and wear resistant. The strain sensor can detect the small strains down to 0.2% with high sensitivity/gauge factor (GF) of 30 within in a strain range of 0–1%, and also shows excellent performance in terms of sensitivity (GF of 34 and 5 within in a strain range of 0–20%, 20–50%, respectively), negligible drift, stability, and durability over 6000 cycles. Moreover, the strain sensor can sense and record large‐scale human body motion even under water‐immersed condition and also exhibits negative temperature coefficient effect with a temperature coefficient of resistance of 0.677%°C−1.

基于石墨烯包覆聚酯编织弹性带的高灵敏，耐用且可穿戴的织物应变传感器，用于人体运动监测
智能电子纺织品因其轻巧，柔韧性，可变形性以及与人体皮肤的便捷相互作用而在柔性和可穿戴设备领域中变得越来越重要。本文报道了一种简单，廉价，可扩展的浸-干-减少方法，该方法以聚酯编织的弹性带（PEB）为平台材料制造了应变传感器，并涂覆了氧化石墨烯，并证明了其潜在的应用前景。可以检测到人体的细微和大范围的变形。PEB是通过将聚酯纱线编织在一系列内部橡胶芯周围而制成的，这使其非常通用，轻便，抗收缩和耐磨。应变传感器可以在0–1％的应变范围内以30的高灵敏度/规格因子（GF）检测低至0.2％的小应变，并且在灵敏度方面（在0％至20％，20％至50％的应变范围内分别为34和5的GF），在6000次循环中的漂移，稳定性和耐用性均可以忽略不计方面表现出卓越的性能。此外，应变传感器即使在浸水的条件下也可以感应和记录人体的大规模运动，并且还具有负温度系数效应，电阻温度系数为0.677％°C-1。
