, resulting in enhanced humidity regulation and improved thermal comfort. In practical applications, the ultrathin silver nanowires/polyvinyl alcohol gel electrode demonstrates outstanding electrophysiological signal acquisition capabilities. Its signal-to-noise ratios for electromyography and electrocardiography match those of commercial gel electrodes, enabling continuous, high-fidelity wireless health monitoring for up to 3 h during daily activities. Furthermore, in electroencephalography measurements, the sensor reliably captures stable alpha waves with minimal background noise, underscoring its excellent real-time frequency response performance.
