Microscope pictures taken under strain show that microwires first undergo a sliding rotation (4C), before starting to break at the overlap areas between microwires (hinge areas) (Fig. ) at higher strains. FEA analysis (Fig. ) confirmed maximum stress concentration at these hinge points. Our current hypothesis is that the minimal initial resistance change results from contact sliding and deformation, while the sharp increase beyond 80% strain reflects progressive microwire breakage, which reduces the ideal case i.
