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.

Abstract: A gas sensor system includes a gas sensing element that includes a gas sensing material and electrodes configured to apply electrical stimuli to the gas sensing material and one or more processors configured to control the gas sensing element. The one or more processors are configured to direct the electrodes to apply the electrical stimuli at two or more different electrical excitation frequencies to the gas sensing material. A first electrical excitation frequency of the two or more different electrical excitation frequencies is configured to provide a quantitative gas response of the gas sensing material, the quantitative gas response including a response drift. A second electrical excitation frequency of the two or more different electrical excitation frequencies is configured to provide a baseline response of the gas sensing material based at least in part on the response drift.

Abstract: A sensor system includes a first sensor to detect environmental conditions of an environment in operational contact with a subject, a second sensor to detect physiological parameters of the subject in operational contact with an asset, and a control unit comprising one or more processors communicatively coupled with the first sensor and the second sensor. The processors receive a first signal from the first sensor indicative of the environmental conditions, and receive a second signal from the second sensor indicative of the physiological parameters of the subject, and determine a relation between the environmental conditions and the physiological parameters based on the first signal and the second signal. The processors determine a responsive action of the asset based on the first signal indicative of the environmental conditions of the environment or the second signal indicative of the physiological parameters of the subject in operational contact with the asset.

Abstract: A system includes a resonant sensor in contact with oil within a gearbox of a rotor system, such as a wind turbine, and one or more processors. The sensor includes electrodes and a sensing circuit that generates electrical stimuli having frequencies applied to the oil at different times during a life of the gearbox. The processors receive electrical signals from the resonant sensor representative of impedance responses of the oil to the electrical stimuli. The processors analyze the impedance responses and determine a concentration of a polar analyte in the oil at different times. The processors calculate a degradation value for the gearbox based on the concentration of the polar analyte. Responsive to the degradation value exceeding a designated threshold, the processors at least one of schedule maintenance for the rotor system, provide an alert to schedule maintenance, or prohibit operation of the rotor system until maintenance is performed.
