Sensitivity towards 10 sccm oxygen flow for Ti nanoparticle decorated carbon nanotube-based sensors for working powers of 5 × 10−3 W (a), 3.5 × 10−2 W (b) showing sensor reproducibility to oxygen cycling, and 4 × 10−2 W (c) showing the two distinct response processes. The testing pressure range for (b) and (c) is the same as the one used in (a).
