Abstract

A sensor device and method to determine an amount of gas in the environment. The sensor device comprises at least one transducer. A sensing material (e.g., a metal-organic framework or a polymer film) is disposed on the transducer, and the sensing material captures an amount of the gas that depends on a temperature of the sensing material and a concentration or partial pressure of the gas. At least one detector or readout circuit is arranged to detect responses of the transducer as it captures gas in the sensing material and to output transducer measurement signals indicative of the responses of the transducer. At least one processor is arranged to process (e.g., demodulate) the transducer measurement signals according to the frequency of the temperature modulation. The processor determines the amount of gas according to the demodulated signals.
