Superelastic Radiative Cooling Metafabric for Comfortable Epidermal Electrophysiological Monitoring

Highlights Efficient sunlight reflectivity and high mid-infrared radiation emissivity are simultaneously realized in a nonwoven metafabric via PTFE microparticle impregnation and thermal-fusion. The metafabric achieves a maximum cooling effect of 17 °C and fully retains its passive cooling performance even under 50% stretching. High-quality electrophysiological monitoring of ECG, sEMG and EEG is realized through compact and homogeneous encapsulation of liquid metal on the elastomeric fibers.
