Stretchable ionic conductors are crucial for enabling advanced iontronic devices to operate under diverse deformation conditions. However, when employed as interconnects, existing struggle maintain stable conduction strain, hindering high-fidelity signal transmission. Here, it is shown that strain-insensitive can be achieved by creating a solid-liquid bicontinuous microstructure. A fiber from polymerization-induced phase separation, which contains solid elastomer interpenetrated liquid ion-conducting phase, fabricated. The spontaneous partitioning of dissolved salts leads the formation robust self-wrinkled interface, fostering development highly tortuous channels. Upon stretch, these meandering channels straightened, effectively enhancing conductivity counteract strain effect. Remarkably, retains till fracture, with only 7% resistance increase at 200% strain. This approach presents promising avenue designing durable cables capable transmission minimal strain-induced distortion.
