Fig. 4

a Stress distribution of Ag NFs networks under tensile strain with different orientations (unidirectional, bidirectional, random). b SEM images of the Ag NFs networks under tensile strain (Top: bidirectional NFs, bottom: random NFs). The NFs break under stress, but there are still conductive paths in the electrodes. c Stress distribution of different patterned Ag NFs electrodes (square, hexagonal and circular) under strain. Stress concentration tends to occur in the corners of the electrodes. d Optical images of large cracks at the corners of square electrodes with the increasing strain (Top to bottom: 15%, 45% and 60%).
