Miniaturised photoacoustic gas sensor based on patented interferometric readout and novel photonic integration technologies (MINIGAS)
Date du début: 1 avr. 2008, Date de fin: 30 sept. 2012,
High-sensitivity gas sensors measure the presence of trace gases. They have a wide range of applications. Finnish SME Gasera has recently developed a MEMS-based mechanism for detecting the pressure waves created in photo-acoustic cells. This innovation can be used to realize infrared gas sensors of extreme sensitivity. Instead of the usual microphone (membrane with capacitive readout) the Gasera c ...
