可穿戴电子纺织品由于其非侵入性健康监测的潜力而获得了巨大的吸引力。然而，由于性能、舒适性、可扩展性和成本差，多功能可穿戴电子纺织品的制造仍然具有挑战性。在这里，我们报告了一个完全印刷的，高导电性，灵活性和可机洗的电子纺织品平台，可以存储能量并监测包括生物信号在内的生理条件。该方法包括在粗糙和灵活的纺织品基底上高度可扩展地印刷石墨烯基油墨，然后进行精细封装，以生产高导电的可机洗电子纺织品平台。生产的电子纺织品非常灵活，适形，可以检测身体各个部位的活动。印刷的平面超级电容器提供的空间电容为3.2 mFcm−2（稳定性为10，000次循环）。我们展示了这种电子纺织品记录大脑活动（脑电图，EEG），并发现与传统的刚性电极相当。这可能会导致一种基于石墨烯的电子纺织品的多功能服装，它可以充当由石墨烯纺织品超级电容器中存储的能量供电的灵活和可穿戴传感器。基于石墨烯的丝网印刷导电、柔性和可机洗的电子纺织品能够捕捉运动，展示其作为活动传感器的潜力平面内全固态印刷纺织品超级电容器显示出相当的性能作为EEG生物信号电极，与当前的刚性临床电极相当健康技术;材料科学;纳米材料
Wearable e-textiles have gained huge tractions due to their potential for non-invasive health monitoring. However, manufacturing of multifunctional wearable e-textiles remains challenging, due to poor performance, comfortability, scalability, and cost. Here, we report a fully printed, highly conductive, flexible, and machine-washable e-textiles platform that stores energy and monitor physiological conditions including bio-signals. The approach includes highly scalable printing of graphene-based inks on a rough and flexible textile substrate, followed by a fine encapsulation to produce highly conductive machine-washable e-textiles platform. The produced e-textiles are extremely flexible, conformal, and can detect activities of various body parts. The printed in-plane supercapacitor provides an aerial capacitance of ∼3.2 mFcm−2 (stability ∼10,000 cycles). We demonstrate such e-textiles to record brain activity (an electroencephalogram, EEG) and find comparable to conventional rigid electrodes. This could potentially lead to a multifunctional garment of graphene-based e-textiles that can act as flexible and wearable sensors powered by the energy stored in graphene-based textile supercapacitors. Graphene-based screen-printed conductive, flexible, and machine-washable e-textiles Able to capture movements demonstrating their potential as activity sensors In-plane all-solid-state printed textiles supercapacitor showing comparable performance Perform as EEG bio-signal electrode comparable to current rigid clinical electrodes Health technology; Materials science; Nanomaterials
