AMUSENS

Gas sensors are essential in multiple sanitary and environmental applications, such as the monitoring of personal or professional exposure to air pollutants, or in the healthcare field to help diagnose diseases or monitor patients using breath analysis. These applications require miniaturized, low power and low-cost gas sensors with good gas selectivity to be integrated into personal devices, product packaging or widely distributed sensor networks. AMUSEMS is aiming to develop a gas sensor platform with flexible selectivity for different gas environments by combining a multi-pixel approach and artificial intelligence. It is based on metal oxide-based detection materials on a unique micro-hotplate platform. Though there are already selective multi-pixel sensors based on different metal oxide materials in the literature, their industrialization is currently limited to a few industrially available materials. By using original additive manufacturing approaches for local deposits in liquid phase and gas phase, we are aiming to expand the choice of materials available and demonstrate their sustainability in platform-scale processing. Artificial intelligence will be used both to accelerate the choice of materials and to merge data to determine specific gas analysis models. Two specific applications targeting personal exposure and healthcare will demonstrate the effectiveness of this multi-pixel platform based on advanced processing provided by AI.
