A Novel Microrheometer for Measuring Rheological Properties of Microquantities of Fluids

摘要

A novel micromachined microrheometer is designed to measure the rheological properties of microquantities of fluid. The measuring principle of this device is based on the interaction of electromagnetic field, superparamagnetic microbeads and fluids. A simple model is developed to test the behaviour of the superparamagnetic microbead with various fluid viscosities.
