This paper reports the sensitivity of second order S2 Lamb mode to liquid characteristics, in which an acoustic Lamb mode resonator LWR based on LiNbO3 ZX (LNO) is numerically studied. The sensitivity of the device to liquids loading is enhanced by incorporating distributed micro-channels in the wave path in order to increase the contact surface between the liquid and the acoustic wave. The obtained results contribute in the development of high sensitivity acoustic sensors for liquids characterization.

Abstract
This paper reports the sensitivity of second order S2 Lamb mode to liquid characteristics, in which an acoustic Lamb mode resonator LWR based on LiNbO3 ZX (LNO) is numerically studied. The sensitivity of the device to liquids loading is enhanced by incorporating distributed micro-channels in the wave path in order to increase the contact surface between the liquid and the acoustic wave. The obtained results contribute in the development of high sensitivity acoustic sensors for liquids characterization.File in questo prodotto:
