Surface acoustic wave (SAW) technology is an extremely versatile technique for the development of gas sensors because of the SAW device's sensitivity to a wide variety of material properties that can change with gas concentration. In the present work

The theory, design and operation of a surface acoustic wave (SAW) hydrogen sulfide (H 2 S) sensor that uses a gold-doped semiconducting metal oxide, tungsten trioxide (WO 3 :Au), film as the gas sensing element is described. It is shown experimentall

A simple theoretical model is applied to the problem of a SAW (surface acoustic wave) gas sensor which operates on the principle of conductivity changes within the sensing film. The model allows the prediction of SAW sensor response for a film of kno

Recently it has been experimentally demonstrated (see J.F. Vetelino et al., 1987) that a surface acoustic wave gas microsensor can detect concentrations of certain gases in the parts per million to parts per billion range. Here, a theoretical model i

Surface generated acoustic waves (SGAW) excited in a piezoelectric medium provide an attractive technology to realize a family of microsensors which are sensitive, portable, cheap and small. In this paper two SGAW microsensors namely, the surface aco
