Figure 5
Time-dependent response and recovery curves of the PANI nanowire array-based sensor exposed to CH4 gas under different strains of (a) 0% strain, (b) 10% strain, (c) 30% strain, (d) 50% strain and (e) 70% strain. (f) Plots of the relative resistance change versus strain for the PANI nanowire array-based sensor exposed to air and CH4 gas.
