摘要： A low power gas sensor is provided for detecting one or more gases in a gas sample. The gas sensor includes a sensor for sensing a desired gas and a heater for heating the sensor. During operation, a controller provides power to the heater to heat the sensor to an operating temperature during a first period of time. Once at the operating temperature, the controller may read the sensor to determine a measure of the detected gas in the gas sample. Once a measurement is taken, and to conserve power, the controller removes the power to the heater allowing the heater and sensor to cool to at or near the ambient temperature for a second period of time. The second period of time may be longer than the first period of time, and in some cases, substantially longer. In some embodiments, the sensor and heater may be thermally isolated from some or all of the remainder of the gas sensor, such as the sensor substrate. This may also help reduce the amount of power that is required to heat the heater and sensor to the operating temperature. The gas sensor of the present invention may be ideally suited for battery powered and/or wireless applications.

摘要： A method and apparatus for monitoring and measuring gas concentrations in combustor applications is provided, wherein the apparatus is a gas sensor having a plurality of electrodes cooperating with a single electrolyte cell for detecting the presence and concentration of gaseous components of a flue gas. A voltage is generated based on the flow of ions caused by differing gas concentrations as detected by electrodes across the electrolyte. The change in voltage is correlated and is used to determine the concentration of detected gases, such as combustible gases, nitric oxides, carbon monoxide, etc., contained in the flue gas. The combustor operation may then be optimized to enhance efficiency and minimize undesired gas concentrations in the flue gas in a desired fashion. A calibration gas may be introduced to calibrate the apparatus and a reference gas may be provided to an electrode as a basis for correlating the concentrations of the gases.

摘要： In an improved amperometric gas sensor, the structure, composition, and electrode potential are adjusted so as to prevent or minimize any unwanted reactivity at the counter and/or reference electrode of any analyte or interfering component of the matrix that may cross over thereto. The sensor is preferably structured so that the product of the analyte reaction at a first working electrode can be reconverted to the original analyte at a counter electrode or at a second working electrode and then reacted again at the first working electrode, with such back-and-forth reactions repeating many times, so as to yield an amplification of the analyte signal.

摘要： The invention relates to sensors of physical quantities such as pressure sensors or acceleration sensors, and more specifically to the mounting of the active part of the sensor on a base (30) bearing connection pins (32). According to the invention, an active part of the sensor, consists for example of micro-machined silicon wafers (10, 12) bearing electronic elements, electrical conductors, and connection pads (22). A base (30) is also prepared, provided with pins (32) whose upper ends are spatially arranged, with each one facing a respective pad (22). The face bearing the pads is applied to the upper part of the pins, and the unit is dipped into an electrolytic bath to deposit metal (34) that rigidly solders the pins to the pads. Preferably, the conductive parts (pins and pads) of the unit are then covered with an insulator (36) to prevent electrical leakage between pins subjected to different potentials.
