Progress and Strategies of Wearable Sensors in Human Health Monitoring Based on Physiological, Biochemical, and Environmental Signals

Flexible wearable sensors, emerging as pivotal tools for health diagnosis and treatment, have garnered significant attention in the present. They facilitate real-time monitoring of human physiological, biochemical, and environmental parameters, demonstrating considerable potential for personalized health monitoring. However, existing literature reviews on wearable sensors predominantly focus on single-signal monitoring. In this paper, the progress of flexible wearable sensors in health monitoring is systematically reviewed, encompassing physiological, biochemical, and environmental signals relevant to human health. Simultaneously, this review provides a comprehensive overview of the design and sensing principles of wearable sensors as well as the strategies for improving their performance. Finally, the development prospects are also discussed, aiming to offer references for the advancement of wearable sensors in health monitoring.
