Surface Acoustic Wave devices are very famous in the application of filters but they are also playing an important role as a sensor for the measurement and control of several physical parameters such as temperature, pressure, humidity, strain etc. They are also useful for the effective detection of different gases, bacteria and water vapors. The performance of these devices is mainly contributed by the mass loading and acoustoelectric coupling. This paper presents the amount of change in acoustic velocity and frequency due to mass loading and acoustoelectric coupling.
