From the Summary section:
Viscosity may change when a formulation ages. Viscosity is a function of a liquid’s permittivity for a specified liquid flow velocity, [> 0] and constant temperature. An economical, compact, low power Capacitive Sensing Unit incorporating a microcontroller, measures quickly relative values of bulk permittivity in liquid samples. The microcontroller provides a standard output signal compatible with Personal Computer equipment for monitoring in real time and digital storage for later, more detailed analysis. A microplate reader for 96 or 24 well microplates can be adapted from measuring optical density to measuring capacitance (a function of permittivity). Liquids will exhibit a characteristic capacitance (permittivity). Viscosity is a function of permittivity at the time of measurement.
