Flexoelectricity in ice electrification events. Credit: Nature Physics (2025). DOI: 10.1038/s41567-025-02995-6 A study co-led by ICN2 reveals that ice is a flexoelectric material, meaning it can produce electricity when unevenly deformed. Published in Nature Physics, this discovery could have major technological implications while also shedding light on natural phenomena such as lightning. Frozen water is one of the most abundant substances on Earth. It is found in glaciers, on mountain peaks an...
