a Cycle-rest-cycle measurement results. b Post anneal test results. I represents the cycling phase, II waiting phase and III post anneal phase. Inks’ increased resistance with bending (I), stable elevated resistance (II), and “healing” with heat treatment (III) clearly visible. c Multiple bending cycle trials: bent samples test results with post annealed samples test results. “bent once” correlates with the first bending cycle; “bent twice” refers to samples that have undergone two bending cycles.
