Figure 3. (A) The tensile stress-strain curves of the composites with Cu@Fe ferrofluid, the Cu@Fe/LM, and the Fe/LM fillers; (B) The relative resistance change of the composite under 200% tensile strain; (C) Cycling stability test under repeated 100% strain for 10,000 cycles of the LME composite; (D) The resistance change of LME composite under different weights from 0 to 1,000 g; (E) The resistance change of LME composite under repeated twisting 180° for 1,000 cycles; (F) The resistance change of LME conductive composite with different bending angles from -180° to 180°. LM: Liquid metal; LME: LM-elastomer.
