A gas sensor device () is configured to measure a predetermined gas of interest and comprises an enclosure () comprising a semiconductor substrate () and defining a first cavity (), an optically transmissive second closed cavity () and a third cavity (). The second cavity () is interposed between the first and third cavities (). The first cavity () comprises an inlet port () for receiving a gas under test, an outlet port () for venting the gas under test. The first cavity () also comprises an optical source () and a measurement sensor (). The second cavity () is configured as a gaseous filter comprising a volume of the gas of interest sealingly disposed in the second cavity (), and the third cavity () comprises a reference measurement sensor () disposed therein.

Gas sensor device and method of manufacturing the same

A sensor device () comprises an emitter device () arranged to emit electromagnetic radiation and having an emission region associated therewith. The sensor device () also comprises a detector device () arranged to receive electromagnetic radiation and having a detection region associated therewith, and an optical system (). The emission region is spaced at a predetermined distance from the detection region. The optical system () defines a plurality of principal rays, a number of the plurality of principal rays intersecting the detection region. The number of the plurality of principal rays also intersect the emission region.

Sensor device

A stress sensor () for detecting mechanical stress in a semiconductor chip () has a Wheatstone bridge formed by four integrated resistors Rto R, the resistors Rand Rbeing p-type resistors and the resistors Rand Rbeing n-type resistors.
