A paper wrist strap similar to the bands worn at festivals can help prevent over-exposure to the sun and reduce the risk of cancer.
The device lets people know when they have been exposed to a certain amount of UV (ultra-violet) radiation by changing color.
The wristbands change color when the sun’s UV rays can start to cause damage.
It operates through an acid-release agent which picks up ultraviolet light and a dye which responds to pH levels in the indicator.
The agent is decomposed by sunlight, leading to the rapid change in color.
The bands will be tailored to different skin types to reflect the different tolerance levels that people have to the sun. For example, a band for someone with fair hair and light skin will change color quicker than a band for someone with dark hair and dark skin.
The technology will be commercialized by Swedish-based company Intellego Technologies, established by Swedish entrepreneur Claes Lindahl.
‘We are very excited about the UV dosimeter technology and we look forward to developing it further and commercializing it,’ said Lindahl. ‘There is a substantial need out in the market for a functional UV dosimeter and we look forward to continuing the process.’
Professor Andrew Mills and Dr Michael McFarlane are both responsible for the original invention and were previously with the University’s Department of Pure and Applied Chemistry. They will now be engaged as consultants to Intellego Technologies.
Mills said: ‘The bands will cost less than 20 cents each because they are disposable and need to be thrown away at the end of the day.
‘The sunburn monitor will make a significant contribution to public health as an affordable, fashionable device which enables people to enjoy the benefits of the sun while at the same time keeping them alert to the risks of over exposure.’ said Fiona Strang, Commercialization Manager with the University of Strathclyde, Glasgow, Research & Knowledge Exchange Services.
