Abstract
Viscosity is an important marker in biological industry and medical predictions. It corresponds to the “thickness” of sample fluid and plays an important role in cardiovascular disease. The device used to measure the viscosity is viscometer. The traditional viscometers utilize mechanical forces for pumping and control sample fluid. In this study, we design a disc-shape centrifugal microfluidic device in order to measure the fluidic viscosity. There are many benefits of disc-shape microfluidic devices as the same with other ordinary microfluidic devices. Furthermore, it is possible and easier to manipulate the flow conditions by controlling the rotational speed. In this study, we use computer simulations to develop the relationship between sample viscosities with their flow conditions and manufacture the microfluidic device. Viscosity is inversely proportion to the flow distance regardless of rotational speed within 0.8 ~ 16m Pa-s.
