Flexible, wireless, multifunctional integrated electronic system for daily wearable gait detection

With the rapid development of Internet of Things and Artificial Intelligence, long-term and wearable gait detection is of great significance for healthcare, rehabilitation, and sports training. However, current wearable gait detection devices are generally less flexible and only a small number of gait features can be detected, which limits their practical applications. Herein, we proposed a novel flexible, wireless, and multifunctional electronic system with proximity and contact pressure sensing capabilities for daily wearable gait monitoring. The system mainly consists of two types of sensing modulus: proximity sensing units for the detection of periodic swing of legs and contact pressure sensing units for swing force sensing of the knee during walking, along with a wireless acquisition module and an APP for data visualization. In addition, the hardware of the system is lightweight and fully-flexible for comfortable wearing on the knees. Benefiting from the above advantages, our system can realize the detection of more gait characteristics related to spatial changes such as stride length, spatial posture of legs, besides the step characteristics, while maintaining the flexibility of the device. It verifies the application potential of flexible integrated electronic system for daily wearable gait monitoring.
