Surface Acoustic Wave Sensing

Sensors have become an integral part of our everyday lives by helping us converting packets of data to make important decisions. The aim of this chapter is to provides introduction to Surface Acoustic Wave (SAW) sensors along with their history, working principle and applications. This chapter provides readers with the theory of the SAW and piezoelectricity. In addition to that, parameter related to the design and different configuration regarding SAW device, along with their fundamental components, are also provided. Lastly, performance evaluation parameters of SAW devices are introduced.
