A Dual Love wave and Impedance-based Sensor: Response Enrichment

This article presents a new approach for the analysis of the electroacoustic response of an acoustic transducer allowing the easy extraction of the dielectric and viscoelastic properties of liquid samples. In this study, different measurements of liquid samples with different physical parameters such as electrical permittivity, viscosity, and density were conducted with Love wave sensors and enabled the decorrelation of the influence of these electrical and mechanical parameters. These results demonstrate the possibility of using a single transducer for multi-physical measurement which will enrich the analysis of biological samples.
