Abstract: A multi-gas sensing system includes a sensing circuit comprising one or more sensing elements. Each sensing element includes a sensing material configured to detect at least one gas analyte. A management circuit is configured to excite the sensing elements with an alternating current at at least one predetermined frequency. The management circuit measures one or more electrical responses of the sensing elements responsive to exciting the sensing elements with the alternating current. The management circuit determines one or more characteristics of the sensing circuit. One or more processors receive the electrical responses of the sensing elements and the characteristics of the sensing circuit. The one or more processors determine a concentration of the at least one gas analyte based on the electrical responses of the sensing elements and the characteristics of the sensing circuit.

Abstract: A sensor system includes a sensing element that includes a sensing material and electrodes configured to apply a first electrical stimuli to the sensing material at an electrical excitation frequency, a modifier assembly including one or more circuits configured to change an electrical impedance of the sensing element, and one or more processors configured to control the modifier assembly. Responsive to exposure of gas to the sensing element, the one or more processors change a linearity of a first electrical signal received from the sensing element by changing the electrical impedance of the sensing element and applying a second electrical stimuli to the sensing material at the electrical excitation frequency.

Abstract: A sensor system includes an electrical circuit having plural leads coupled with one or more sensing regions. The sensing regions include gaps having sensing materials that detect an analyte of interest. The gaps close responsive to the sensing material corresponding to the gaps detecting the analyte of interest. One or more processors communicatively coupled with the electrical circuit receive electrical signals from the electrical circuit indicative of the gaps closing responsive to the sensing material of the corresponding gaps detecting the analyte of interest. The electrical circuit is in a closed position in the presence of the analyte of interest. The sensor system is configured to consume an increased amount of power when the electrical circuit is in the closed position relative to the electrical circuit in an open position responsive to the one or more of the gaps closing. A responsive action is determined based on the electrical signals.
