Under variable ambient conditions such sensors suffer from cross-sensitivity from interferent gases and from fluctuation s (drift) of their response because single-output sensor designs mathemati cally do not allow gas-selectivity and/or drift correction. We break this status quo by developing a new generation of gas sensors\, known as multiv ariable sensors with several independent responses. By our designs\, these sensors are first-order analytical instruments. In this talk\, we will sh ow that individual multivariable gas sensors quantify several gases and re ject interferences\, which is mathematically not feasible using convention al sensor designs. Next\, we will show that such multivariable gas sensors have the ability for self-correction for sensor drift. Our multivariable gas sensors operate in the radio-frequency (RF) and optical portions of th e electromagnetic spectrum. We self-correct for the baseline drift by sens or operation at more than one frequency of wavelength. Our approach for th e drift self-correction should allow implementations of gas sensors in div erse applications that cannot afford weekly\, monthly\, or quarterly perio dic maintenance\, typical of traditional analytical instruments.\n\nSpeake r(s): Dr. Radislav A.
