Strain-dependent I-V curves and resistance versus strain plots. (a) Strain-dependent I-V curves of a 180-nm Ti film on PDMS substrate. Here, the strain was applied by uniaxial stretching. I-V curve of a pure PDMS sheet is also shown for comparison. Resistance versus strain plots of the sample under (b) simple stretching and (c) mixed straining of bending and stretching. In (c), blue square symbols represent resistances measured from the second straining cycle.
