Abstract Electromagnetic interference (EMI) shielding fabrics are crucial in addressing the increasingly serious electromagnetic pollution. To meet wearable requirements, stretchability and thermal comfortability often desired, but which still challenging. Herein, a stretchable EMI fabric is fabricated via electrospinning coupled with biaxial pre‐stretching spraying, block stacking wrinkled silver nanowire (AgNW)/Ti 3 C 2 T x MXene network coated on one side of electrospun thermoplastic polyurethane (TPU)/polydimethylsiloxane (PDMS) fabric. As expected, structure protects conductive from fracture during stretching process, so as to realize strain‐invariant electrical conductivity. Thus, exhibits performance over 40 dB when subjected 10–50% uniaxial strains or 21–125% strains. More importantly, white TPU/PDMS black AgNW/MXene enable passive radiative cooling heating, respectively. The high mid‐infrared emissivity (97.5%) solar reflectance (90%), thus reducing skin temperature by ≈4.9 °C. heating absorptivity (86.6%) photothermal effect increased ≈5 Therefore, fabirc Janus‐type dual‐mode personal management promising future products.

Abstract Electronic textiles harmoniously interact with the human body and surrounding environment, offering tremendous interest in smart wearable electronics. However, their wide application faces challenges due to lack of stable stretchable power electrodes/devices multifunctional design. Herein, an intrinsically liquid metal‐based fibrous anode for a Zn‐ion battery (ZIB) is reported. Benefiting from feature superior deformability metal, optimized Zn ion concentration distribution (002) deposition behavior are observed, which result dendrite‐free performance even under stretching. With strain 50%, ZIB maintains high capacity 139.8 mAh cm −3 (corresponding 83.0% initial value) after 300 cycles, outperforming bare fiber‐based ZIB. The seamlessly integrates sensor, Joule heater, wirelessly charging device, provides supply signal monitoring personal thermal management, holding promise electronic textiles.
