Research progress in flexible wearable sensing and intelligent recognition techniques

Flexible wearable sensors can be stably integrated with the human body to continuously measure multiple physiological and motion parameters. They may play important roles in health monitoring, sports monitoring, precision medicine, human-computer interaction, and so on. The combination of flexible wearable sensors and artificial intelligence technology demonstrates the advantages of using continuous dynamic multi-parameter signal measurement to determine and identify diseases, actions, and speech. This paper introduces the applications of flexible wearable devices in physical signal, chemical signal, and image signal sensing, and reviews the methods and progress in combining flexible wearable devices and artificial intelligence from the aspects of hardware platforms, processing techniques, and analysis approaches. The intelligent recognition techniques based on flexible wearable sensing systems have been presented, and the challenges that include device integration, data transmission, energy supply, and so on have also been analyzed, followed by our perspectives of the future trends of flexible wearable electronics.
