摘要
柔性可穿戴器件是未来器件发展的重要趋势,而应变传感器是可穿戴电子设备的重要组成部分,可用于人体运动检测、个人健康与医疗监护、智能机器人等方面~[1]。理想的可穿戴应变传感器应具有良好的柔性和一定的弹性,并具有高灵敏度、快速响应性以及轻质、耐用性等特点。碳材料,例如碳纳米管、石墨烯、碳纤维等,因具有一定的机械柔性、良好的导电导热性、出色的物理化学稳定性等优点,是制备柔性可穿戴器件的理想材料选择之一。我们利用碳纳米管、石墨烯和天然生物质等作为材料基础,通过对其微纳米结构的调控和宏观结构的设计,制备了一系列碳基柔性可穿戴器件,例如,碳纳米管压力传感器、洋葱状石墨烯压力传感器、碳化丝素蛋白织物应变传感器~[2]等,并展示了它们在人体运动检测(如关节运动、脉搏、微表情、呼吸、发声)和电子皮肤等方面的应用,相关研究为高性能、低成本柔性可穿戴材料与器件的制备提供了新的途径。
The development of flexible electronics and equipment attracts significant interests in recent years. Low-dimensional carbon materials are one kind of ideal materials for flexible electronics. It is of great importance to explore low cost and scalable preparation approaches for high performance flexible carbon materials-based wearable electronics. In this work, we use carbon materials, including carbon nanotubes, graphene, and carbon fibers as the key materials and fabricate a series of flexible wearable sensors. For example, we fabricate highly sensitive pressure sensor based on graphene onion films made from chemical vapor deposition, ultra-stretchable and highly sensitive strain sensors based on a carbonized-silk-fabric with a plain-weave-structure. We further demonstrated their applications in detection of human motions, and in capture and reconstruction of human body movements, showing their great potentials for applications in wearable devices and intelligent robots. Our strategy provides new approaches for the low-cost and high performance production of flexible electronics, promising its high potential for practical applications.
