Machine Learning-Guided Design of Perovskite Oxides for High-Temperature Oxygen Sensing

Presentation slides for 2025 MRS Fall Meeting & Exhibit. Reliable oxygen sensors are vital for high temperature applications including combustion engines, steel production, and petrochemical refining, yet identifying stable, high-performance materials for such environments remain challenge. We apply machine learning (ML) to predict the atmospheric oxygen partial pressure–dependent conductivity of perovskite oxides, combining data from the Materials Project and published datasets.
