Abstract
Methods and sensors for selective fluid sensing are provided. A sensor includes a resonant inductor-capacitor-resistor (LCR) circuit and a sensing material disposed over a sensing region. The sensing region comprises at least a portion of the LCR circuit. Temperature-dependent response coefficients of inductance L, capacitance C, and resistance R properties of the LCR circuit and the sensing material are at least approximately 5 percent different from one another. The difference in the temperature-dependent response coefficients of the properties of the LCR circuit and the sensing material enables the sensor to selectively detect analyte fluids from an analyzed fluid mixture substantially independent of temperature.
