New wearable electronic sensing and monitoring devices can provide users information to help them determine if their environment is exposing them to specific health risks, such as skin cancer. Those technologies are especially good at detecting unsafe levels of exposure to solar ultraviolet radiation, a main cause of skin damage. In an article coauthored by Fulton Schools biological design doctoral student Alyssa Henning, ASU researchers offer a detailed examination of current wearable devices that sense ultraviolet radiation — including smartwatches, fitness trackers, running watches that work in tandem with smartphones, tablets and computers. The researcher offer evaluations of the capabilities and potential effectiveness of the technologies.
