英文摘要	This paper presents the experimental work on the measurement of unadulterated human whole blood viscosity using a capillary-based microfluidic viscometer. The viscosity was measured by monitoring the time-varying length and mean advancing velocity of the blood column inside the viscometer. A high-aspect-ratio microfluidic channel is preferred for the device geometrical configuration. Theoretical modeling and numerical algorithms were applied to obtain the blood viscosity over a wide range of shear rates. Power law and Carreau-Yasuda models were used to model the non-Newtonian behavior of the human whole blood. The proposed approach is uniquely applicable for small sample volume (<2 mu L), and short measurement time (<2min). A wide range of shear rates (varying from of 71.4s(-1) to 5492.1s(-1)) is produced in a single test.; CPCI-S(ISTP); dkang@caltech.edu; 1-4
