Proc. SENSOR Conference, Nürnberg, May 2007
Microacoustic liquid sensors like quartz crystal resonators  and surface acoustic wave devices  have
proved particularly useful alternatives to traditional viscometers. However, for non-Newtonian or more complex
liquids such as emulsions it has been shown that microacoustic devices may not be sufficient to detect
rheological effects which are present on the macroscopic scale . In contrast, cantilever based liquid sensors
sense in a rheological domain which is more comparable to that probed by laboratory instruments .
However, cantilever sensors do not show a simple relation between sensor parameters and liquid parameters.
In our contribution, we aim at clarifying this relation using an experimental approach combined with
an analytical model.
