Development of a new Mobile Gas Sensing Technology
Today, Senseair AB, AMO GmbH, KTH Royal Institute of Technology, Oxford Instruments Plasma Technology Ltd, Graphenea Semiconductor SL, Universität der Bundeswehr München, Catalan Institute of Nanoscience and Nanotechnology, and SCIPROM Sàrl announced the launch of the ULISSES project, a European collaboration to develop a new class of miniaturised optical gas sensors on a chip. The project partners will collaborate to combine silicon photonics with 2D materials, to enable fully integrated optical gas sensing nodes for the Internet of Things (IoT) that can be manufactured in large volumes at low cost and achieve performance improvements in terms of size and power consumption. The development would enable personal gas sensors embedded in wearable devices, as well as installed in public infrastructures, such as in street lighting, on buses and in taxis, or even in small unmanned aerial vehicles. The new technology aims to empower the general public to monitor and put demands on their air quality.
Gas sensors are already widely used in industry and agriculture, to ensure the safety of personnel and to monitor and automate processes. However, the rising general awareness of the importance of urban indoor and outdoor air quality is now driving demand for accurate, low-cost and mobile gas sensor technology. Optical gas sensors offer the highest sensitivity, stability and specificity in the market. However, their current cost, power consumption, and size hinder them from being widely employed by the general public. ULISSES technology will enable compact, low-cost and low-power gas sensor nodes to be networked for comprehensive and real-time monitoring of air quality in urban areas. This new approach will provide valuable information to city planners, employers, and landlords to ensure a healthy indoor and outdoor environment.
By leveraging recent breakthroughs of the ULISSES partners on waveguide integrated 2D materials-based photodetectors, 1D nanowire mid-IR emitters, and mid-IR waveguide-based gas sensing, ULISSES targets a three-order-of-magnitude reduction in sensor power consumption, thus permitting maintenance-free battery-powered operation for the first time. Furthermore, ULISSES will implement a new edge-computing self-calibration algorithm that leverages node-to-node communications to eliminate the main cost driver of low-cost gas sensor fabrication and maintenance.
