Liquid viscoelasticity probed by a mesoscale piezoelectric bimorph cantilever

The viscoelastic properties of fluids are key to their performance in industries ranging from biotechnology to the automotive industry. Traditionally, fluid viscoelastic properties are monitored with rheometers but these are expensive, require a skilled operator, function over a relatively limited frequency range and are not suitable for in situ monitoring. Piezoelectric cantilevers capable of in situ assessment of the rheological properties of...
