While ambient sensing technologies like WiFi DensePose provide macro-level human tracking, they lack the ability to capture vital micro-level physiological parameters. Here, we present a "macro-micro" health monitoring system that couples ambient WiFi sensing with a novel, fully integrated flexible epidermal patch. The flexible patch features a multi-layered architecture encapsulating customized electronic circuits within compliant elastomers and an advanced AgNW-hydrogel interface. It is capable of continuously monitoring heart rate (HR), respiratory rate (RR), and motion kinetics via integrated surface electromyography (sEMG) and multi-axis accelerometry. Mechanical characterizations demonstrate the patch's durability under 30% tensile strain, bending, and twisting, while interface evaluations confirm superior skin compliance compared to commercial electrodes. By establishing a four-layer architecture (Perception, Fusion, Edge Computing, Application), this system fuses real-time electrophysiological data with spatial WiFi DensePose mapping, offering a comprehensive paradigm for personalized healthcare in smart living spaces.
