Figure 3. Characterization of the tensile and electrical properties of the EGaIn-AgNPs biphasic structure. (A) Mechanism diagram of the EGaIn-AgNPs structure maintaining conductivity under stretching; (B) Microstructure of IMC cracks and EGaIn paths under stretching; (C) Local surface scanning results; (D) Effect of different Ag ratios on conductivity; (E) Resistance response of EGaIn-AgNPs structures with different Ag ratios under different strains; (F) Resistance response test of samples with 20% Ag content (EGaIn:Ag=80:20) under a frequency range of 0.025~0.2 Hz (0.025, 0.05, 0.1, 0.2 Hz); (G) Cyclic stability of the EGaIn-AgNPs structure within 10,000 cycles under 100% strain. The insets show the initial 20 cycles and the final 20 cycles, respectively; (H) Temperature stability test of EGaIn-AgNPs structure; EGaIn-AgNPs: eutectic gallium indium-silver nanoparticles.
