The present invention is a multidimensional integrated detection and analysis system (MIDAS) for any gas or fluid that transfers or accepts electronic charge (including but not limited to CH4, CO2, CO, NOx, SOx, H2O, NH3, NHx). MIDAS allows for the development of a highly sensitive, selective, and expedient sensor platform capable of uniquely identifying adsorbed molecules based on simultaneous measurement of truly orthogonal responses based on work function (φ), capacitance (C), and/or conductance (σ) changes.
