Fig. 1: Principle of wearable Electromagnetic interference (EMI) shielding metasurfaces with frequency selective transmission.

a Expanded view of the multilayer configuration of the EMI-shielding metasurface. (False colors). b Schematic of the EMI shielding metasurface composed of silver nanowire (AgNW)/ Eutectic Gallium-Indium (EGaIn) conductive materials patterned on a Polydimethylsiloxane (PDMS) substrate with strain-controlling structures. c A schematic of the EMI shielding metasurface illustrating consistent selective transmission of the target frequency (blue) while blocking untargeted frequencies (red) under mechanical bending. d A schematic of the EMI shielding metasurface illustrating consistent selective transmission of the target frequency while blocking untargeted frequencies under mechanical stretching. e A schematic of a seamlessly integrated wearable EMI shielding metasurface into clothing. f Images of fabricated EMI shielding metamaterial under uniaxial stretching (left: X-axial direction, right: diagonal direction) Scale bars: 5 cm. g Simulated transmission spectra of our EMI shielding metasurface at 30% mechanical strain, showcasing consistent electromagnetic performance even under mechanical strain.
