Self‐Incandescent Heating‐Driven Microstructural Consolidation of Biscrolled Cu/CNT Yarns for Reduced Frequency‐Dependent AC Resistance

Small Methods, EarlyView.
Self‐incandescent heating (SIH) induces microstructural consolidation in biscrolled Cu/CNT yarns, resulting in improved electrical conductivity, a smaller frequency‐dependent increase in AC resistance within the measured range, and stable electrical performance under repeated bending.
