New material provides everyday UV radiation detection
Researchers from the University of Turku, Finland, developed a reusable synthetic material that changes color when it detects UV radiation. Called SensoGlow, the photochromic material is made from a synthetic version of hackmanite. Hackmanite changes color when exposed to sunlight and is a naturally occurring mineral. SensoGlow also indicates the intensity of the radiation by changing the depth of the color. The darker the color, the more radiation is present. Because scientists create the new mineral in the lab, it reacts to any or all of UVA, UVB or UVC radiation. Color-changing materials are not new; what is new with SensoGlow is its durability.
