Abstract
A system, device and methods, for determining at least two analytes, wherein the system and device include at least one resonant sensor circuit that includes a sensing material that predictably affects the resonant complex impedance response of a sensor electrode. The sensing material has at least two material properties that change when the materials are exposed to two or more analytes. The system and device also include a processor that generates a multivariate sensor response pattern that is based at least in part on a change in the two material properties of the sensing material.
