Abstract

A system that includes a sensor for measuring a resonant impedance spectral response of an inductor-capacitor-resistor (LCR) resonator and correlating the measured response of one or more spectral parameters to one or more characteristics of the fluid. Such characteristics may be the age or health of the fluid and/or the identification of and concentration of components in the fluid.
