TECHNOLOGY DESCRIPTION
The technology is a NOx sensor based on Prussian Blue allowing a high sensitivity of measurement. This technology uses the reversible oxidation under NO of Prussian Blue and thus allows to guarantee a strong selectivity with a low sensitivity to moisture.DEVELOPMENT STAGES
- Today, a proof of concept has been achieved with detection results below 100 ppm.
- The objective of the program will be to miniaturize this process and bring the detection threshold below 25 ppm.
COMPETITIVES ADVANTAGES
- Selective sensor with sensitivity <100 ppm today and < 25 ppm in the future
- Low sensitivity to humidity
- Fast response time
- Easy to miniaturize
