ferroelectrics

Ferroelectrics are a type of materials that have a unique property: they can retain a permanent electric polarization even when an external electric field is removed. This means they can "remember" their electric state, similar to how magnets can hold a direction. Commonly used in electronics and sensors, ferroelectrics enable functions like data storage, voltage control, and piezoelectric effects, where mechanical stress produces an electric charge. Their distinctive behavior arises from the alignment of electric dipoles within the material, influenced by temperature and external fields, making them crucial in many modern technologies.
