Figure 6 (a) Real time phase of a 3-cycle ZIF-8 film-coated SAW sensor measured in wired mode for various gases exposure. Inset is the response of a 2-cycle film-coated SAW sensor to pure CO2 and CH4 for repeated exposure. (b) Wirelessly measured real time phase of a 2-cycle film-coated SAW sensor for pure CO2 (70 L/min). Shown wireless measurement was performed using commercial whip antennas.
