Adaptable multi-pixel gas sensor platform for a wide range of appliance and consumer markets
Gas sensors are crucial in the personal and industrial monitoring to analyze personal exposure to air pollutants or to critical gases, to control product quality such as in the food industry, in health care by analyzing gases from human body and using breath analysis combined with wearable sensors for personal stress estimation. These applications require miniaturized low power and low-cost gas sensors with good gas selectivity to be integrated in personal devices, in product packaging or in widely distributed sensor networks.
AMUSENS aims at developing a gassensor platform with flexible selectivity to different gas environments by combining a multi-pixel approach and artificial intelligence to adapt the data analysis to the targeted applications. It is based on metal oxide sensing materials on micro-hotplate platform, which are already available on the market for low power applications, but suffer from a lack of selectivity. Gas-selective multi-pixel sensors based on different metal oxide materials have been demonstrated, but their industrialization is limited to few industrially available materials. By using original additive manufacturing approaches for local liquid-phase and gas-phase depositions, we aim at extending the choice of available materials and demonstrate their sustainability in wafer-scale processing. Artificial intelligence will be used to accelerate the choice of materials, for data fusion to determine specific patterns in the gas analysis and to optimize sensor calibration through calibration transfer models. Three specific applications targeting personal exposure and health care will demonstrate the adaptability of the platform, based on an analysis of the users’ requirements. AI interpretation will be facilitated using model-agnostic interpretability analysis of the AI-based models for calibration transfer and on the use-case models.
The project brings together 11 partners from across Europe, with a total budget of over €8.5 million, and a duration of 48 months.
I-SENSE Group/ICCS proudly joins AMUSENS from May 2025 and will give a new boost to the project through:
- The development of interpretable AI models for calibration transfer and signal analysis (WP15 & WP16),
- Participation in the co-design process to ensure user-aligned tools,
- And real-life testing with human participants in the stress estimation use case, combining breath analysis with wearable devices (WP10).
