Itâ€™s always a bummer when you spent a few hours in the sun and donâ€™t realize until later that youâ€™ve charred your skin. If this happens to you as much as it happens to me, a new monitor to detect sun overexposure might be of interest to you.
The ultra-violet ray detecting wristband, developed at the University of Strathclyde, changes colors as the risk of overexposure to the sun progresses, giving visual warnings for when itâ€™s time to hit up some shade. An acid-release agent in the band gradually brakes down with exposure to UV radiation, which triggers a pH-sensitive dye that turns from yellow to pink.
Swedish-based company Intellego Technologies will be commercializing the wristband, which will be available in spring 2013. Claes Lindahl, the company founder, says they are â€œvery excited about the UV dosimeter technology and we look forward to developing it further and commercializing it.â€ He added that there is a â€œsubstantial need out in the market for a functional UV dosimeter and we look forward to continuing the process in collaboration with the University of Strathclyde.â€
According to Cancer Research U.K., in 2008, there were 200,000 new cases worldwide of Malignant melanoma, the deadliest form of skin cancer. Reducing sun exposure by providing a visual indication sounds like one of the easiest ways to help cut that number and show people how little exposure it takes to damage your skin. As a fair-skinned redhead, I will definitely be trying one of these out.
