Abstract:
In recent years,with the rapid development of the internet of things and artificial intelligence technologies,multimodal intelligent perception devices capable of integrating multiple sensing capabilities such as vision,touch,and odor.The multimodal intelligent perception devices have shown broad application prospects in the fields of information acquisition and processing.Due to their high specific surface area,tunable electronic structure and multi-physical field sensing properties,two-dimensional materials are ideal candidates for building high-performance,multi-modal sensing devices.In addition,2D material sensor devices are also capable of real-time analysis of multi-dimensional data and machine learning,which can realize self-learning and self-optimization functions.Firstly,reviews the current research status of intelligent perception devices based on 2D materials.Then,analyses the application characteristics of 2D materials in the fields of electrical,optical,mechanical and chemical sensing,covering intelligent gas sensing,intelligent biosensing,intelligent optoelectronic sensing,intelligent stress sensing and multimodal intelligent sensing.Finally,the challenges faced by 2D material-based intelligent perception devices in practical applications are discussed,such as homogeneity of material preparation,stability of devices,multifunctional integration,intelligence and data processing,and future research trends are envisioned.
