Abstract

The one-dimensional transmission-line model has been applied successfully for the description of the transduction mechanism of acoustic-wave-based microsensors, e.g.. In this model, the surface acoustic load acting at the interface between the acoustic device and the adjacent medium plays the dominant role and reflects changes in mass, density, or film thickness of a coating (gravimetric effects) as well as (visco-)elastic properties of the material (non-gravimetric effects). One important requirement of the transmission-line model is the continuity of particle displacement and stress at the interface. This has the disadvantage that it cannot allow for the existence of slip. This contribution introduces a new concept for the treatment of slip between an acoustic wave device and a contacting solid film or a contacting liquid. In this concept slip modifies the acoustic load acting at the surface of the sensor.
