This new band was unveiled at London’s Wearable Technology Conference and will prevent skin cancer, according to Engineering and Technology Magazine. This UVA/UVB alert system was created by Karin Edgett and her husband, Shahid Aslam, NASA scientist. Karin feels there are challenges computing SPF.

“We feel like there isn’t a good tool for people to measure themselves in terms of how much sun is safe; it’s all a guessing game. If you use sunscreen there’s no correlation, according to the FDA, between SPF and how much time you should spend in the sun. So you’re guessing even if you use sunscreen”

Considering most people visit a beach or hang out at a local pool and end up getting burned, it’s probably a wise investment.

The device, expected to be released into the market in April, is equipped with a light sensor registering the amount of direct sunlight the skin receives. It combines the information with the knowledge of the user’s sensitivity level and triggers an alarm when the time spent on direct sunlight exceeds safe limits.

This month we have already seen wristbands that detect pollutants. The trend seems to be growing, but how many bands are we willing to wear? Wouldn’t it be nice if one band could do it all?
