Various embodiments of a gas sensor device and method of fabricating a gas sensor device are provided. In one embodiment a gas sensor device includes a base substrate, an electrolyte layer disposed on the base substrate and a plurality of potentiometric sensor units electrically coupled to the base substrate. Each potentiometric sensor unit includes an electrolyte layer disposed on the base substrate, a sensing electrode comprising tungsten oxide (WO) and platinum (Pt), a reference electrode comprising Pt, and a plurality of connectors coupled to the plurality of potentiometric sensors to connect the plurality of potentiometric sensors in series.

Miniaturized gas sensor device and method

Systems and methods for discriminating among volatile compounds is provided using a semiconductor junction structure or sensor device. Sensor devices of the present disclosure employ a combination of hole carriers (p-type) and electron carriers (n-type) metal oxides deposited, for example, on a gold microspring array designed so that it has several leads that are at different distances from each other.

Obtaining selectivity in gas sensors via a sensor array system composed of P and N type material

An NO sensing system includes an inlet for receiving an original sample, a humidifier, fluidly communicating with the inlet, and a first sensor. The original sample is fluidly transmitted through the humidifier and exits the humidifier as a humidified sample having a humidity above a predetermined level. The first sensor generates a potential difference in response to presence of NO in the humidified sample. The potential difference is indicative of a level of NO within the original sample.
