PROBLEM TO BE SOLVED: To provide a sensing method and system.SOLUTION: A system 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 a fluid. Such characteristics may be the age or health of the fluid and/or the identification of and concentration of components in the fluid.SELECTED DRAWING: Figure 1 |
