D7.4 - MEMS-based Measurement of Rheological Fluid Properties

I. Dufour, E. Lemaire & B. Caillard
Silicon microcantilevers can be used to measure the rheological properties of complex fluids. In the method presented in this paper, the measurement of the microcantilever’s dynamic spectrum is used to extract the hydrodynamic force exerted by the surrounding fluid on the microcantilever and consequently the rheological fluid properties. The originality of the proposed method relies in the fact that not only may the viscosity of the fluid be measured but also the fluid’s viscoelasticity, i.e.,...
