University of Nottingham investigates secret information storage using 3D printing

A new, 3D printable smart material developed at the University of Nottingham in the UK has presented researchers with a novel way of storing, and hiding, information. Laden with photochromic particles, the material changes color in reaction light, then turns back again when exposed to air. “In theory,” explains project co-lead Dr. Graham Newton, “it would […]
