a Photograph of a 10 cm-long FSHC integrated into a commercial glove. Inset shows high-resolution images before and after applying 50% tensile strain (scale bar, 2 mm). b Real-time voltage response of the FSHC integrated into a fabric glove during repeated finger bending (B) and spreading (S) motions. c Voltage signals recorded under static strains of 0–200% followed by recovery, demonstrating electrical stability. d Schematic illustration of the self-powered actuation system, in which the FSHC supplies electrical energy to a twisted CNT fiber-based torsional actuator. e Voltage profiles of serially connected FSHCs (1–4 units, labeled i–iv). f Voltage profiles of parallelly connected FSHCs (1–4 units, labeled I–IV). g Paddle rotation angle of a two-end-tethered twisted CNT fiber driven by the FSHC, with inset photographs of the actuator in the initial state, during self-powered actuation, and after recovery.
