SPIN Centre for Chemical Engineering


Our research activities deal with the electrical properties of solids interacting with a gas, and are applied to the development of gas and particle sensors.
They cover the entire value chain from the physico-chemical principles of gas-solid interactions and their modeling, the development of chemical sensors based on semiconductor or ionic conductive materials using various shaping technologies (screen printing, inkjet printing, etc.), the implementation and evaluation of sensors performance on laboratory test benches or on site, and data processing.
