1. An apparatus for measuring a viscosity of a non-Newtonian fluid, comprising:
a Parylene coated quartz tuning fork for immersion in the non-Newtonian fluid;
an electronic circuit to excite a vibration of the Parylene coated quartz tuning fork and measure one or more vibrational parameters of the Parylene coated quartz tuning fork;
a computer processor configured to determine a Newtonian viscosity from the vibration of the Parylene coated quartz tuning fork based, at least in part, on a Stokes flow hydrodynamic model; and
a memory, coupled to the computer processor, and storing a calibration curve configured to convert the Newtonian viscosity to a non-Newtonian viscosity.
