    May 21, 2024 · An electret is a material that possesses a static electric field. This word is a combination of “electricity” and “magnet.” The material used in electrets is a special dielectric, an insulator with a special ability to retain a significant amount of strong electric field where it was immersed at the time of its manufacture.
