Ultra-broadband infrared gas sensor for pollution detection

Periodic Reporting for period 1 - TRIAGE (Ultra-broadband infrared gas sensor for pollution detection)

Okres sprawozdawczy: 2021-01-01 do 2022-02-28

Air pollution is one of the largest risk factors for disease or premature death globally, yet current portable monitoring technology cannot provide adequate protection at a local community level.

-TRIAGE will develop a smart, compact and cost-effective air quality sampling sensor network for the hyperspectral detection of all relevant atmospheric pollution gases
-Resolution and selectivity will be two orders of magnitude better than current solutions and for lower cost
-Cloud-based deep-learning algorithms will enable automated short-term alerts and long-term trend analysis
-Extensive testing in urban settings with Swedish and Swiss environmental agencies and transport companies.

TRIAGE aims to provide smart photonic sensing for environmental air pollution monitoring, by prototyping a portable, high-performance, sensing system, based on cutting-edge photonic technology for pervasive air quality sensing. By accessing the infrared atmospheric window between 2-10 µm, high specificity and sensitivity for molecular gases is achieved as each molecule has its characteristic infrared absorption spectrum in this ‘fingerprint’ region. As such, TRIAGE can detect minute traces of molecules in complex gas mixtures and will provide real time information and analysis.

In TRIAGE, several technologies will be developed, integrated and demonstrated:

Hardware
-2-10 micron supercontinuum sources by NORBLIS and DTU
-Rugged low noise 2 µm pump laser by NKT Photonics
-High-performance multi-pass absorption cell by Senseair
-Infrared detector modules by VIGO System
-FT spectrometer by Radboud University
-The system will be integrated by CSEM

Data analysis
-Reference database by Radboud University
-Analysis and deep learning algorithms by CSEM

Demonstration
-Linköping University will be responsible for the tests of functionality and long-term demonstration of the TRIAGE system.
-Demo activities will be conducted in real world settings (urban environments and on transport networks)
-Several key players from the TRIAGE-NET will be involved, including national agencies relating to environmental air monitoring and instrumentation manufacturers

The project starts on 01-Mar-2021 and will run for three years.
Good progress has been made in all areas of the project.

-The first iteration of fibres for supercontinuum generation has been produced at DTU.
-NKT is developing an all-EU 2 um pump laser for the TRIAGE supercontinuum source.
-The first NORBLIS supercontinuum sources have been delivered to the partners to begin integration into the TRIAGE system.
-Two iterations of IR detector have been developed at VIGO.
-Senseair has designed and built the first multi-pass cell.
-Radboud has built the FTS and worked closely to transfer this technology to CSEM.
-CSEM has developed the first machine learning algorithms to automatically calculate gas composition from a mixture of gases based on the IR absorption spectrum.
-CSEM has upgraded a similar system from the H2020 FLAIR project (https://www.h2020flair.eu/home) to generate data 24/7 which can be used to train the ML algorithms in advance of the completion of the TRIAGE system.
-A range of use cases have been identified, and the TRIAGE-NET (https://triage-project.info/links/triage-net) has grown to eight active end users and industrial companies.
-LiU has identified urban and rural demo sites for the final stages of the project.
-Working with the NET, a number of niche applications have been identified which could yield important exploitation routes for the technology.
-TRIAGE has established the ECREAM cluster of thirteen H2020 projects working on environmental, agricultural and food monitoring technology (https://triage-project.info/links/ecream).

A summary of this work is given in this public presentation from Mar-2022.
