U-M materials science and engineering assistant professor John Heron discusses a new material developed by U-M researchers that could reduce the energy consumption of the world’s computing devices as well as advance sensors for medical and security devices. This material is “at least twice as magnetostrictive” and more cost-efficient; magnetostriction causes the “buzz of fluorescent lights and electrical transformers.” The faculty expert explains the development of this material, which is from inexpensive iron and gallium, as well as the future implementation of this material.
