Here, we report the adsorption effect of NO$_2$ on ZnO (100 nm) nanowires. We have studied the effect of adsorbed NO$_2$ molecules on ZnO nanowire-based energy harvester for an exposure time of 1, 2, 3, 4, 5 and 6 h in a sealedchamber at 50 ppm which yielded piezoelectric voltage of 543.6 mV, 834.6 mV, 1.071 V, 1.78 V, 1.969 V and 2.835 V, respectively. We have thoroughly investigated the behaviour of ZnO nanowires in the presence of NO$_2$ and observed a maximum output piezoelectric voltage of 2.835 V with a power density 158.2 mW cm$^{-2}$. This is the first time that ZnO based piezoelectric energy harvester is being used for the voltage enhancement in the presence of NO$_2$. We have used vertically integrated nanowire generator (VING) structure. X-ray diffraction pattern revealed the growth orientation ofZnO nanowires were along the $c$-axis from the substrate. ZnO nanowires were grown on indium tin oxide-coated polyethylene terephthalate substrates
