- There has been growing interest of an accurate and rapid
viscosity monitoring of liquid medium in various fields
such as, oil industry, medicine, and food industry [1,2].
Especially, the blood viscosity is essential factor to
diagnose and monitor the cardiovascular diseases
(hypertension, ischemic heart disease, and acute
myocardial infarction). In spite of the importance of blood
viscosity information, there is some quite a sure method
for measurement of blood viscosity.
Recently, because conventional rheometers have some
limitation for application in these fields, microresonatorbased
viscosity measurement technique has been in the
spotlight. Microresonators such as, microcantilever,
microbridge, or microdiaphragm have been used to probe
the viscosity of liquids by measuring the resonant
frequency change of microresonators. The resonant
frequency of microresonators can be changed by viscosity
and density of surrounding liquid.
