Flexible sensors play a crucial role in electronic skin technology, with carbon materials showing excellent performance in this field. Researchers are focusing on developing multifunctional flexible sensors, while integrating diverse cutting-edge technologies can lead to more advanced e-skin systems.
Electronic skin (e-skin) is driving significant advances in flexible electronics as it holds great promise in health monitoring, human-machine interfaces, soft robotics, and so on. Flexible sensors that can detect various stimuli or have multiple properties play an indispensable role in e-skin. Despite tremendous research efforts devoted to flexible sensors with excellent performance regarding a certain sensing mode or property, emerging e-skin demands multifunctional flexible sensors to be endowed with the skin-like capability and beyond. Considering outstanding superiorities of electrical conductivity, chemical stability, and ease of functionalization, carbon materials are adopted to implement multifunctional flexible sensors. In this review, the latest advances of carbon-based multifunctional flexible sensors with regard to the types of detection modes and abundant properties are introduced. The corresponding preparation process, device structure, sensing mechanism, obtained performance, and intriguing applications are highlighted. Furthermore, diverse e-skin systems by integrating current cutting-edge technologies (e.g., data acquisition and transmission, neuromorphic technology, and artificial intelligence) with carbon-based multifunctional flexible sensors are systematically investigated in detail. Finally, the existing problems and future developing directions are also proposed.
