由于下一代传感器设备在制造过程、食品和环境控制、医学、疾病诊断、安全和国防、航空航天等领域的广泛应用，其发展受到学术界和工业界的极大关注。目前的挑战包括开发低成本、超高和用户友好的传感器，这些传感器具有高选择性、快速响应和恢复时间以及小尺寸。这些新型传感器的关键要求通常与先进的纳米级传感材料有关。其中，石墨烯及其衍生物已经证明了克服这些挑战的理想特性，并已合并为各种应用中最流行的传感平台之一。近年来，广泛的石墨烯组件具有不同的结构、形态和尺度（从纳米、微观到宏观），用于设计新的高性能传感器件。在此，本研究介绍并讨论了以纤维、薄膜和泡沫/气凝胶形式组装的基于石墨烯的一维、二维和三维宏观形状的上层结构的合成策略的最新进展。系统地回顾和讨论了这些材料在气体和蒸汽、生物医学、压阻应变和压力、重金属离子和温度传感器中的最新应用，并比较了它们的传感性能。
Development of next-generation sensor devices is gaining tremendous attention in both academia and industry because of their broad applications in manufacturing processes, food and environment control, medicine, disease diagnostics, security and defense, aerospace, and so forth. Current challenges include the development of low-cost, ultrahigh, and user-friendly sensors, which have high selectivity, fast response and recovery times, and small dimensions. The critical demands of these new sensors are typically associated with advanced nanoscale sensing materials. Among them, graphene and its derivatives have demonstrated the ideal properties to overcome these challenges and have merged as one of the most popular sensing platforms for diverse applications. A broad range of graphene assemblies with different architectures, morphologies, and scales (from nano-, micro-, to macrosize) have been explored in recent years for designing new high-performing sensing devices. Herein, this study presents and discusses recent advances in synthesis strategies of assembled graphene-based superstructures of 1D, 2D, and 3D macroscopic shapes in the forms of fibers, thin films, and foams/aerogels. The fabricated state-of-the-art applications of these materials in gas and vapor, biomedical, piezoresistive strain and pressure, heavy metal ion, and temperature sensors are also systematically reviewed and discussed, and their sensing performance is compared.
