The Acoustics Driven Microfluidic Extensional Rheometer (ADMiER) utilises micro litre volumes of liquid,
with viscosities as low as that of water, to create valid and observable extensional flows, liquid bridges that
pinch off due to capillary forces in this case. ADMiER allows the study fluids that have been beyond
conventional methods and also study more subtle fluid properties. We can observe polymeric fluids with solvent
viscosities far below those previously testable, accentuating elastic effects. Also, it has enabled the testing of
aqueous solutions of living motile particles, which significantly change fluid properties, opening up the potential
for diagnostic applications.
