A monitor developed at the University of Strathclyde for
preventing the risk of overexposure to the sun is now available for sale
online.
The Smartsun device, worn as a waterproof wristband, changes
colour according to the amount of exposure the wearer has to UV (ultra-violet)
radiation. It starts off yellow but turns pink as exposure increases, warning
users to get out of the sun.
The monitor’s sensitivity to ultraviolet light means it can
alert the wearer to the danger before it is visible on the skin.
