These modes are found to be very different to the parameters. For example  the A01 mode is very sensitive to the liquid's density but the A03 mode is sensitive to its sound velocity. The measurements of the attenuation with S0 mode can give out liquid's viscosity after its density been determined by A 01 mode. That could be a way to distinguish an unknown liquid with high sensitivity or to solve the problem of the selectivity of label free detection on biosensors. 2011 IEEE.   Multi-Parameter sensing in liquid using a lamb wave based microsensor (EI CONFERENCE) 会议论文  OAI收割 2008 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications, SPAWDA 2008, December 5, 2008 - December 8, 2008, Nanjing, China 作者:  Li F.;  Wu Y.-H. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 The characters of zero anti-symmetric (A0) and zero symmetric modes (S0) of Lamb wave sensor loaded with liquid were investigated and compared in the paper. It was found that due to the their different acoustic penetration depths inside the liquid the changes of the surface characteristics of the sensor and the characteristics of liquid near the surface can be identified respectively by combined A0 and S0 modes simultaneously. At the same time  the mass sensitivities of both A0 mode and S0 mode of a 2m Lamb wave sensor were demonstrated experimentally. It was proved that S0 mode has higher sensitivity to surface mass changes and the mass sensitivity of the acoustic sensor can be improved further.
