Abstract
A method includes receiving multiplexed sensor data from a sensor array. The multiplexed sensor data includes first data from a first sensor of the sensor array and second data from a second sensor of the sensory array. The first data includes first frequency information of a first cantilevered element, the first cantilevered element including a coating material having an affinity for a compound and no diffusion barrier. The second data includes second frequency information of a second cantilevered element, the second cantilevered element including the coating material and a diffusion barrier. The diffusion barrier inhibits mass transfer to the second cantilevered element. The method also includes conditionally generating, based on an analysis of the first data and the second data, an output. The output is conditioned on the first frequency information and the second frequency information indicating more than a threshold amount of the compound present at the sensor array.
