The measure of hygrometry is a current approach for soil monitoring in geophysical applications. In that case, in-situ subsurface earth moisture control is tackled with the design of wireless and free from battery sensors interrogated from the surface. Since the most significant impact of humidity on ground physical properties is on the relative permittivity εr, the measurement is based on the capacitive...
This work deals with the possibility to create a high temperature surface acoustic waves (SAW) sensor based on the use of a new piezoelectric material : Ba2TiSi2O8.The wave propagation in the material is at first studied and compared to another material used for harsh environment : LiTaO3. Then a SAW resonator on Ba2TiSi2O8 is designed.
