    摘要： Embodiments of the subject invention relate to a gas sensor and method for sensing one or more gases. An embodiment incorporates an array of sensing electrodes maintained at similar or different temperatures, such that the sensitivity and species selectivity of the device can be fine tuned between different pairs of sensing electrodes. A specific embodiment pertains to a gas sensor array for monitoring combustion exhausts and/or chemical reaction byproducts. An embodiment of the subject device related to this invention operates at high temperatures and can withstand harsh chemical environments. Embodiments of the device are made on a single substrate. The devices can also be made on individual substrates and monitored individually as if they were part of an array on a single substrate. The device can incorporate sensing electrodes in the same environment, which allows the electrodes to be coplanar and, thus, keep manufacturing costs low. Embodiments of the device can provide improvements to sensitivity, selectivity, and signal interference via surface temperature control.

    摘要： Sensors (10, 40) accurately measure the concentration of an oxide compound, such as nitrogen oxide NO.sub.x, in a gas mixture (11) which can include oxygen O.sub.2. The sensors (10, 40) each comprise a chamber (12, 42) adapted to receive the gas mixture (11) as well as first and second electrochemical cells (16, 17) for consuming oxygen and/or the oxide compound in the chamber (12, 42). The first electrochemical cell (16) comprises a first internal electrode (16a) inside the chamber (12, 42), a first external electrode (16b) outside the chamber (12, 42), and a first electrolyte body (14') therebetween. The second electrochemical cell (17) comprises a second internal electrode (17a) inside the chamber (12, 42), a second external electrode (17b) outside the chamber (12, 42), and a second electrolyte body (14") therebetween. The first and second electrolyte bodies (14', 14") are permeable to oxygen ions. Significantly, the first and second internal electrodes (16a, 17a) are metal oxides having a perovskite lattice structure, which generally exhibit high relative selectivity between oxide compounds, including NO.sub.x, and O.sub.2. The electrical characteristics of the first and second electrochemical cells (16, 17) are manipulated and/or monitored in order to determine the concentration of NO.sub.x within the chambers (12, 42) and the gas mixture (11).

    摘要： A solid state electrochemical cell (10a) for measuring the concentration of a component of a gas mixture (12) includes first semiconductor electrode (14) and second semiconductor electrode (16) formed from first and second semiconductor materials, respectively. The materials are selected so as to undergo a change in resistivity upon contacting a gas component, such as CO or NO. An electrolyte (18) is provided in contact with the first and second semiconductor electrodes. A reference cell can be included in contact with the electrolyte. Preferably, a voltage response of the first semiconductor electrode is opposite in slope direction to that of the second semiconductor electrode to produce a voltage response equal to the sum of the absolute values of the control system uses measured pollutant concentrations to direct adjustment of engine combustion conditions.

    摘要： A device for the concurrent oxygen generation and control of carbon dioxide for life support system involves two stages, where a first stage removes CO2 from an exhalent side of a ventilation loop and a second stage employs Ceramic Oxygen Generators (COGs) to convert CO2 into carbon and O2. The first stage includes a plurality of chambers and means to switch the ventilation loop through at least one of the chambers, where CO2 removal is carried out before discharge of the CO2 depleted gas to an inhalant side of the ventilation loop, and to exclude the ventilation loop from the remaining chambers of the first stage, where these chambers are placed in communication with the second stage. The second stage has two portions separated by the COGs such that CO2 and the formed carbon remain on an intake portion from the O2 rich atmosphere on the exhaust side, which is plumbed via a metering valve to introduce the O2 rich atmosphere to the inhalant side of the ventilation loop.
