Quartz crystal impedance studies at 10 MHz of viscoelastic liquids and films

A rapid measurement of the components R and XL of AT-cut quartz crystal electroacoustic impedance at 10 MHz is reported. Parametric impedance plane plots (XL vs. R) are introduced to analyse the effect of mass/volume and viscoelastic changes in the films and liquids in contact with the quartz crysta...
