Developed at the university of strathclyde in glasgow for intellego technologies, a ‘sunburn monitor wristband’ is able to help prevent over-exposure to the sun by indicating to users when they have been exposed to a certain amount of UV radiation. The monitor works by changing from yellow to pink, acting as a visual reminder as the risk of contracting a sunburn increases. the system operates through an acid-release agent which picks up ultraviolet light and a dye which responds to pH levels in the indicator.
