Recent Progress in Ohmic/Schottky-Contacted ZnO Nanowire Sensors

Figure 16

(a) I-V characteristics of a ZnO NW glucose sensor under different compressive strains, no glucose added. The inset shows a digital image and an optical microscopy image of the ZnO NW glucose sensor. (b) I-t characteristics of another ZnO NW glucose sensor in different glucose concentrations, no external strains applied. The inset presents a schematic of the experiments setup. (c)-(d) Absolute and relative current response of the ZnO NW glucose sensor in different glucose concentrations, with compressive strain ranging from 0 to −0.79%, respectively. (e)-(f) Absolute and relative current response of the ZnO NW glucose sensor under different compressive strains, with glucose concentration ranging from 0 to 1.50 g/L, respectively [18].
