Innovative sensor technology for efficient and portable gas detection devices

Gas sensors developed in a European project now enable the implementation of cheaper and smaller instruments with equal or higher speed and sensitivity than current laboratory-grade instruments. Production of super-sensitive and portable measuring devices is made possible by a photo-acoustic gas sensor with innovative parts such as an interferometer and a MEMS cantilever. While a laser is needed as infrared light source for the highest sensitivity, novel IR LEDs are sufficient for measuring fairly small gas concentrations in lower cost portable devices.Sensitive, portable measuring
