Abstract
To improve selectivity of existing sensors and sensor arrays, we developed a concept of multivariable resonant sensing. Here we demonstrate its performance on several types of transducers in their wireless implementations. These transducers include inductor-capacitor-resistor (LCR), quartz crystal microbalance (QCM), and split ring resonator (SRR) devices. Our individual sensors demonstrate part-per-billion and part-per-trillion detection limits and successfully compete in their selectivity with sensor arrays.
