a Schematic illustration of the experimental setup (upper panel) used to detect inert gas pressure. Corresponding digital photograph (bottom panel). Comparison of IV plots from eight diagonal pixels in the devices b AD12 and c AD20. Comparison of the real-time responses from eight diagonal pixels with an argon flow rate of 140 SCCM in the devices d AD12 and e AD12. Spatial distributions of pressure responses at an argon flow rate of 140 SCCM from addressable devices f AD12 and g AD12.
