面向24h身体行为监测应用的柔性可穿戴智能材料应用研究进展OA

Modern lifestyles are associated with significant public health concerns,including sedentary behavior and sleep disorders.Flexible wearable intelligent materials,characterized by excellent biocompatibility and continuous signal acquisition capabilities,are becoming a pivotal technology for the precise 24 h monitoring of physical behaviors(e.g.,activity,sedentariness,and sleep).This review aims to dissect the current research landscape in this field,from theoretical foundations to engineering applications.It first explores the use of flexible electronic interfaces in physical activity monitoring,highlighting how material innovations have enabled the expansion from macroscopic biomechanical sensing to microscopic metabolite tracking.The role of these materials in identifying sedentary behaviors is then analyzed,focusing on high-sensitivity designs for capturing postural transitions and assessing physiological load.For sleep health,the discussion centers on unobtrusive material systems for long-term monitoring of respiratory and sleep rhythms.Furthermore,to support the extended operation of such wearable devices,this review synthesizes advanced self-powering and energy storage solutions,such as triboelectric nanogenerators,photovoltaics,and biofuel cells.Persistent challenges are identified,including the lack of standardized validation,limited battery life,and insufficient understanding of the complex correlations between behavior and physiology.Future progress is expected to depend on the convergence of material innovation,multimodal sensor fusion,optimized artificial intelligence algorithms,and large-scale clinical trials,ultimately contributing to a comprehensive smart health management ecosystem.
