A Rayleigh surface acoustic wave (RSAW) resonator with Cu2+-PANI-SnO2 nanocomposite thin film is investigated as a gas sensor for detecting the presence of nitric oxide (NO) in air. The sensor developed in this work was sensitive to NO gas at room temperature. It is shown that the sensor had a frequency shift of 0.45 ppm when it was exposed to 12 ppb NO. This RSAW sensor also exhibited repeatability to the presence of NO gas. Especially, the presented sensor showed highly selectivity with NO gas to separate from NO2 and CO2 gases.
