Vibrating silicon-based microcantilever proved to be microrheometer. One calibration step and non iterative calculations are enough to investigate the viscosity and density of fluids over higher frequency than that obtained by mechanical rheometers. The accuracy of measurements is dependent on the cantilever geometry. Moreover, combination of the results of more than one cantilever broadens the frequency measurement limits.
