Title:Modelling of a micro-rheometer in the spectral domainAuthor(s):Thomas Voglhuber-Brunnmaier, Erwin Reichel, Bernhard JakobyAbstract:For online process monitoring purposes, like in oil condition monitoring, in medical analysis or in food production, microsensors can be used to measure the properties of liquids. A liquid is characterized by several parameters with mass density and shear viscosity being of primary importance. The introduced membrane rheometer consisting of a sample cell covered with two Lorentz-force actuated membranes is modelled in the spectral (wavenumbers) doamin. Valuable properties like frequency responses, penetration depths of shear waves, and power dissipation regimes are calculated efficently by the method.Booktitle:Tagungsband zur Informationstagung Mikroelektronik 10Editor(s):Gornik, Grimm, Jakoby, Riedling,SchoitschPage Reference:page 135-140, 6 page(s)Publishing:4/2010Number:56
