Environmental monitoring
Increasing awareness and new regulations for safety and emission control have created a strong demand for low-cost, reliable gas sensors.
The Microsystems and nanotechnology department has been involved in the development of infra-red (IR) gas sensors based on silicon microsystems technology. This includes realization of key components such as IR sources, tunable filters and silicon based IR detectors. A miniature photoacoustic gas sensor is currently under development within the EU - supported prosjekt NETGAS.
Gas sensor for indoor air quality control
SINTEF is an active partner in several technology platforms for MEMS-based gas sensors, and CO2 sensors in particular. The MONTIE project web-page and final report provides an overview of current state-of-the-art in Air Quality / Environment Gas Sensors (MEMS-based). The workshops (activities) and presentations held during the MONTIE project give an overview and introduction to the application field and motivation for several on-going research projects. How to navigate in the web-page is best described in the report, which may be downloaded free of charge from the Nordic Innovation web-site.
Infra-red light source
- Blackbody IR radiation from a heated silicon resistor
- High modulation speed due to low thermal mass
