Resonator Sensors for Rheological Properties - Theory and Devices

Description

Resonators are sensitive to their external loading. When a surface is exposed to a liquid, rheological properties can be measured. In contrast to laboratory methods, resonator sensors feature high sensitivity at low viscosity and applicability for online monitoring tasks. On the other hand, the accuracy decreases significantly at higher viscosities. Here, the concept and theory is investigated with the example of an electrodynamic resonator sensor where a sessile droplet of sample liquiddeposited on the sensitive area. The in-plane motion leads to a dominant shear-wave interaction between the fluid and the oscillating structure.
