Multifunctional wearable e-textiles have been a focus of much attention due to their great potential for healthcare, sportswear, fitness, space, and military applications. Among them, electroconductive textile yarn shows great promise for use as the next-generation flexible sensors without compromising properties and comfort of usual textiles. Recently, a myriad of efforts have been devoted to improving performance and functionality of wearable sensors. However, the current manufacturing process of metal-based electroconductive textile yarn is expensive, unscalable, and environmentally unfriendly. In this work, we report the preparation of multifunctional reduced graphene oxide/linen (RGO/LN) fabrics through the reduction and the followed suction filtration. As-prepared RGO/LN fabric could serve as the methane gas sensor, which exhibited high sensitivity, remarkable reliability and feasibility. Furthermore, the RGO/LN fabric sensor exhibited good moisture permeability and air permeability. The present work reveals that RGO/LN fabric has great potential as wearable smart devices in personal healthcare applications.

多功能可穿戴电子纺织品因其在医疗保健，运动服，健身，太空和军事应用中的巨大潜力而​​备受关注。其中，导电性纺织纱线在不损害常规纺织品的性能和舒适性的前提下，有望用作下一代柔性传感器。近来，为提高可穿戴式传感器的性能和功能做出了大量努力。然而，当前的金属基导电纺织纱线的制造工艺昂贵，不可缩放且对环境不利。在这项工作中，我们报告了通过还原和随后的抽滤制备多功能的还原性氧化石墨烯/亚麻布（RGO / LN）织物。准备好的RGO / LN织物可用作甲烷气体传感器，具有很高的灵敏度，显着的可靠性和可行性。此外，RGO / LN织物传感器具有良好的透湿性和透气性。目前的工作表明，RGO / LN织物在个人医疗保健应用中具有可穿戴智能设备的巨大潜力。
