Textile‑Scale Liquid–Metal Fibers with Strain‑Invariant Conductivity Enable Absorption‑Enhanced EMI Shielding

Caption

  • A Fe-EGaIn/TPU core–sheath fiber is fabricated by coaxial wet spinning, enabling high stretchability together with Joule heating, infrared stealth, strain-invariant conductivity, and electromagnetic interference (EMI) shielding.
  • The fiber exhibits strain-invariant conductivity, showing only a -6% resistance change at 100% strain; COMSOL simulations corroborate the tensile-loading mechanism underpinning this behavior.
  • A Fe-EGaIn/TPU textile woven from orthogonally interlaced horizontal and vertical fibers delivers absorption-dominated EMI shielding with only 7 wt% Fe.
