A stretchable, skin-mountable and wearable strain sensor is important because of its possible applications in monitoring our daily life and work, such as robotic intelligent equipment, health-monitoring, human motion detection and remote precise diagnosis. A linen fabric-derived carbon (LDC) has been rationally integrated with 2D graphene and 1D silver nanowires by impregnation of the linen fabric with a graphene oxide suspension followed by carbonization and final impregnation with a suspension of silver nanowires. The Ag nanowires/graphene/linen-derived carbon (Ag-GLDC) composite sensor exhibits excellent stretchability (>60%), good cycling stability, and high sensitivity with gauge factors of 11.2, 36.8 and 74.5for strains of 0–20%, 20%–40%, 40%–60%, respectively. The composite sensor has been successfully used to monitor the vigorousmotion of human body joints (wrist, knee and elbow), suggesting its potential use in human motion detection. This work provides a new method for the preparation of flexible and wearable composite strain sensors with high performance.

可拉伸，可安装在皮肤上且可穿戴的应变传感器非常重要，因为它可能用于监视我们的日常生活和工作，例如机器人智能设备，健康监视，人体运动检测和远程精确诊断。通过用氧化石墨烯悬浮液浸渍亚麻织物，然后碳化并用银纳米线悬浮液进行最终浸渍，已将亚麻织物衍生的碳（LDC）与2D石墨烯和1D银纳米线合理地整合在一起。Ag纳米线/石墨烯/亚麻衍生碳（Ag-GLDC）复合传感器具有出色的可拉伸性（> 60％），良好的循环稳定性和高灵敏度，对于0–20％的应变，其规格系数为11.2、36.8和74.5，分别为20％–40％，40％–60％。该复合传感器已成功用于监测人体关节（腕部，膝盖和肘部）的剧烈运动，表明其在人体运动检测中的潜在用途。这项工作为制备具有高性能的柔性可穿戴复合应变传感器提供了一种新方法。
