Sensing Performance

In the study, a MEMS-based gas sensor is presented, which consists of a sensing thin film deposited by RF sputtering and annealed at 375°C. The structure and surface pattern of the thin film are analyzed by XRD and SEM. The sensor consists of a substrate, Pt interdigitated electrodes and an SnO2 sensing layer. As concentration of oxygen changes, a change in the electrical conductivity of the SnO2 film is caused. The experimental results show that the measured resistance increases as the concentration of oxygen increases at a working temperature of 300°C. A good oxygen sensing performance is presented in the study.

The Relationship

To improve the temperature stability, response speed and sensitivity of surface acoustic wave (SAW) gas sensor, the relationship between the sensing region of the resonator for SAW gas sensor and the sensitivity of sensor is studied, a specific resonator with big space topology structure is proposed. A SAW resonator with high temperature stability is investigated from the viewpoint of piezoelectric material, cut type and fabrication process. A nano-wire bundle based SAW gas sensor with big specific-surface-area is proposed.
