Electromagnetic interference (EMI) shielding fibers are crucial in practical uses for their flexibility and one-dimensional form. However, application is limited by poor compatibility between EMI components fiber substrates, high electromagnetic wave reflectivity. Herein, a core/shell-structured introduced, featuring core of Ga-In-Sn-Zn alloy, Carbopol, air bubbles, shell ionogel formed from copolymerized acrylamide acrylic acid. A single achieves total effectiveness ∼35 dB within the 2-18 GHz range, which increases to ∼70 when three stacked. Remarkably, demonstrates enhanced performance following stretching recovery. Additionally, it exhibits excellent impedance matching, with reflection power coefficient as low 0.14 at 10 GHz. The fiber's mechanism encompasses shielding, absorption shielding─attributable conduction loss polarization loss─and multiple shielding. Furthermore, shows potential strain sensor. This research offers an effective strategy creating flexible capabilities EM reflection.
