A Study on the Gas/Humidity Sensitivity of the High-Frequency SAW CO Gas Sensor Based on Noble-Metal-Modified Metal Oxide Film

In order to improve the response characteristics of the surface acoustic wave (SAW) sensor to trace gases, a SAW CO gas sensor based on a Pd–Pt/SnO<sub>2</sub>/Al<sub>2</sub>O<sub>3</sub> film with a high-frequency response performance is proposed in this paper. T...
