GAS SENSOR AND METHOD OF DETECTING ONE OR MORE GASES

摘要

Gas sensor and method of detecting one or more gases. This invention refers to a gas sensor and a method for collecting one or more gases. An arrangement incorporates a collection electrode arrangement maintained at similar or different temperatures,In such a way that the sensitivity and selectivity of the type of device may have the fine tuning adjusted between different pairs of absorption electrodes. A specific modality relevant to a gas sensor arrangement for monitoring combustion exhaust and /or by -products Of reaction reactionChemistry. A device modality related to this invention operates in high temperatures and can withstand hostile chemical environments. The arrangements of the device are made on a single substrate. Devices can also be made on individual 15Al substrates and monitored individuallyBecause they are part of an arrangement on a single substrate. The device can incorporate catchment electrodes into the same environment,Which allows the electrodes to be coplanar and,This way,Keep manufacturing costs down. The modalities of the device may provide improvement in sensitivity,Signal selectivity and interference through surface temperature control.
