Wearable sensors are advancing personalized healthcare and environmental safety, yet integrating multimodal sensing remains challenging due to material incompatibility, cross-sensitivity, interference. To address this gap, we present a monolithic wristband-integrated platform for simultaneous physiological monitoring. The system integrates NO2, UV irradiance, epidermal temperature, human pulse signals. A TiO2/WS2 heterojunction-based resistive transduction matrix, as the core material, achieves room-temperature NO2 detection (theoretical limit of 14.4 ppb) with 12-month stability, intensity measurement (0.024-1.68 mW/cm2), temperature monitoring (25-50 °C, sensitivity 0.22%/°C), arterial waveform analysis (P-T-D peak resolution). hybrid neuroevolutionary algorithm (GA-BP) decouples photo-gas interference, reducing quantification errors <3.5%. Flexible electronics selective encapsulation (PDMS, PET shielding) ensure mechanical durability accurate signal acquisition. demonstrates multifunctional capabilities that enable point-of-care health monitoring, bridging diagnostics exposure assessment.
