Original Kurzfassung:
In this contribution the design, fabrication, and characterization of a miniaturized process
rheometer in plastic electronics technology is presented. This device type features electromag-
netic excitation and an inductive readout mechanism. The resonance behavior of several vibra-
tion modes of the clamped–clamped structure is determined. The modeling of the fluid–structure
interaction allows the derivation of rheological parameters of the fluid under investigation from
the measured frequency response. Vibration amplitudes of several micrometers and low opera-
tion frequencies make these devices suitable for the analysis of complex liquids like suspensions
and emulsions. Several prototypes were manufactured and characterized in various test liquids.
