Intelligent sensing technologies based on flexible wearable sensors: A Review

Flexible wearable sensors, characterized by their stretchability, flexibility, lightweight, high sensitivity, and the ability to dynamically and continuously measure multiple parameters, have been widely applied in areas such as physiological health monitoring, human-computer interaction control, real-time motion monitoring, and personalized medical assistance. With the development of artificial intelligence technology, the integration of flexible wearable sensors with artificial intelligence technologies such as machine learning has become increasingly profound. This integration has facilitated the emergence and development of intelligent sensing systems with human-like perception capabilities, garnering growing attention towards flexible wearable intelligent sensing technology. This paper focuses on introducing various sensor mechanisms, intelligent sensing algorithms, and practical applications of flexible wearable intelligent sensing technology. The challenges and possible development directions of flexible wearable smart sensing technology, encompassing aspects such as power supply, multimodal sensing capability, preparation materials, processing and fabrication techniques, and smart sensing algorithms, are also discussed and prospected. Such a review can provide a reference for research in the field of flexible wearable smart sensing technology.
