Background, Motivation and Objective Accurately measurement and monitor on methane concentration is an urgent problem to be solved in the purpose of safety and process control in homes, industries and mines. Compared with traditional methane sensors, surface acoustic wave (SAW) based sensor exhibits many advantages as simplicity, small size, high sensitivity and working at room temperature. The SAW based methane sensor developed in this contribution was composed of a differential resonator-oscillator, and a supermolecular cryptophane-A thin film coated onto the sensing device. The differential oscillation frequency was picked for sensor performance evaluation.
