摘　　要：Flexible and wearable sensors have drawn ex-tensive concern due to their wide potential applications inwearable electronics and intelligent robots. Flexible sensorswith high sensRivity, good flexibility, and excellent stabilityare highly desirable for monitoring human biomedical signals,movements and the environment. The active materials and thedevice structures are the keys to achieve high performance.Carbon nanomaterials, including carbon nanotubes （CNTs）,graphene, carbon black and carbon nanofibers, are one of themost commonly used active materials for the fabrication ofhigh-performance flexible sensors due to their superiorproperties. Especially, CNTs and graphene can be assembledinto various multi-scaled macroscopic structures, includingone dimensional fibers, two dimensional films and three di-mensional architectures, endowing the facile design of flexiblesensors for wide practical applications. In addition, the hybridstructured carbon materials derived from natural bio-mate-rials also showed a bright prospect for applications in flexiblesensors. This review provides a comprehensive presentation offlexible and wearable sensors based on the above variouscarbon materials. Following a brief introduction of flexiblesensors and carbon materials, the fundamentals of typicalflexible sensors, such as strain sensors, pressure sensors,temperature sensors and humidity sensors, are presented.Then, the latest progress of flexible sensors based on carbonmaterials, including the fabrication processes, performanceand applications, are summarized. Finally, the remainingmajor challenges of carbon-based flexible electronics are dis-cussed and the future research directions are proposed.近年来,柔性传感器因其在可穿戴电子设备和智能系统中的广阔应用前景而备受关注.柔性可穿戴传感器具有高灵敏度、良好的机械柔性、优异的稳定性、人体友好性等特点,在人体运动与生理信号监测、环境因素检测等方面具有极大的应用潜力.一般而言,柔性传感器的性能主要取决于敏感材料的选择与器件的结构设计.得益于其优异的性能和灵活多样的组装结构与形貌,碳材料是目前应用最广泛的敏感材料之一.根据需求,纳米碳材料可组装为各类宏观结构,比如一维的纤维,二维的薄膜和三维的块体结构,从而可用于制备各种柔性传感器以适应不同的需求.此外,通过规模化、低成本的高温碳化工艺可以将天然生物质材料转化为柔性、导电碳材料,并用于高性能柔性传感器制备.本文针对碳材料在柔性器件中的应用,综述了各类碳材料的制备方法与结构特点,并重点介绍了其柔性可穿戴传感器的制备与性能.第一部分简要介绍了柔性传感器与碳材料;第二部分概述了四类典型柔性传感器的工作原理与性能特点;第三部分详细综述了一维、二维和三维碳材料的制备方法与其在柔性传感器的组装、性能与应用方面的最新研究进展;最后,总结了碳基柔性传感器领域的发展现状,讨论了该领域所面临的挑战及其未来前景.
