RESONATOR-BASED EVALUATION OF FLUID VISCOELASTIC PROPERTIES

摘要

An analysis technique for determining complex qualitative and quantitative contributions to the viscoelastic properties of a film in contact with or in close proximity to a surface. Based on an assumption that the viscosity of the surface of a fluid film that is opposite to a surface at which the film interacts with the surface changes negligibly, the invention derives representative parameters for the mass and elasticity of the film as a whole as well as a qualitative parameter that is representative of a typical single particle within the film. These representative parameters can be used to classify the film, and in the case of blood or other bodily fluids, can be used to identify pathological conditions. The invention is applicable to all types of liquids that physically interact with a surface, e.g. by exhibiting a coupling effect, adhesion or the like.
