AI streamlines search for new ceramics that generate electricity

A tedious process of trial and error is normally required to discover ceramic materials that generate electricity under mechanical stress. Known as piezoelectric ceramics, these valuable next-generation materials can replace batteries that power small electronic devices, like sensors. To streamline the research process, a team led by materials science researchers at Penn State introduced a new framework that combines an existing artificial intelligence (AI) model with human expertise to uncover these materials. To test the new approach, researchers developed a new piezoelectric composite and incorporated it into an energy harvester, which converts vibrations or movements into electricity.
