Abstract:
This paper presents a sensitivity study of acoustic hydrogen gas sensors. The study emphasises on the comparison between sensitivity of Surface Acoustic Wave (SAW) hydrogen gas and new acoustic hydrogen sensors based on Lamb waves. To highlight this comparison, a parametric model based on the variation of mechanical and physical properties of Palladium sensitive layers has been implemented. This results show that SAW wave devices are more sensitive to Young’s modulus variations than Lamb Acoustic Wave devices.
