Abstract

Using a one-dimensional approach the electric admittance |Y| of a quartz crystal microbalance (QCM) is calculated as a function of frequency depending on material properties as well as the acoustic impedance of an arbitrary loading. Several solutions for the shift of specific frequencies are derived and methods presented to either suppress or compute the influence of parasitic effects. Measurements of high and complex viscosities are possible. The model has been confirmed experimentally.
