"Phys.org is reporting on a study published in Nature Physics involving ICN2 at the UAB campus, Xi'an Jiaotong University (Xi'an) and Stony Brook University (New York), showing for the first time that ordinary ice is a flexoelectric material -- meaning it can generate electricity when subjected to mechanical deformation," writes longtime Slashdot reader fahrbot-bot. In addition, we identified a thin 'ferroelectric' layer at the surface at temperatures below -113C (160K)," explains Dr. Xin Wen, a member of the ICN2 Oxide Nanophysics Group and one of the study's lead researchers. The surface ferroelectricity is a cool discovery in its own right, as it means that ice may have not just one way to generate electricity, but two: ferroelectricity at very low temperatures, and flexoelectricity at higher temperatures all the way to 0 C." This property places ice on a par with electroceramic materials such as titanium dioxide, which are currently used in advanced technologies like sensors and capacitors.
