Wearable Multimodal Sensing System for Synchronously Health–Environmental Monitoring via Hybrid Neuroevolutionary Signal Decoupling

), epidermal temperature monitoring (25-50 °C, sensitivity of 0.22%/°C), and arterial pulse waveform analysis (P-T-D peak resolution). A hybrid neuroevolutionary algorithm (GA-BP) decouples photo-gas interference, reducing quantification errors to <3.5%. Flexible electronics and selective encapsulation (PDMS, PET shielding) ensure mechanical durability and accurate signal acquisition. The platform demonstrates multifunctional capabilities that enable point-of-care health and environmental monitoring, bridging personalized diagnostics with exposure assessment.
