Abstract This study introduces a novel Room‐Temperature Processable Stretchable Conductive Composite (RTPSC), uniquely combining room‐temperature processability, stretchability, and conductivity. Unlike traditional conductive materials requiring thermal or UV curing, which can damage heat‐sensitive components cause substrate distortion, RTPSC uses Styrene‐Butadiene‐Styrene (SBS) elastomer blended with silver fillers paraffin oil. composition enables rapid solidification within five minutes at room temperature, mitigating risks. Surface ligands on flakes are replaced oleylamine, resulting in uniform distribution enhanced resistance to acids, bases, oxidation. The composite exhibits low contact (0.1 Ω across 7.7 mm 2 ) maintains robust mechanical electrical properties under extensive deformation, thanks its high adhesion force (704.5 gF/25 mm). Notably, change remains 0.15 even after 1800 cycles 50% strain. RTPSC's viscosity be finely tuned by adding solvents secondary fluids, enabling various printing techniques from spray omni‐directional printing. adaptability allows intricate patterning delicate structures via versatile connections between stretchable electrodes rigid through These capabilities provide design flexibility ease of repair, making highly suitable for innovative development maintenance electronic devices.
