UV Wristband Tells Sunbathers When to Reapply Sunscreen
A specialized paper wristband helps prevent over-exposure to the sun and reduce the risk of skin cancer.
A team at Strathclyde University in Scotland is developing a wristband that will help sunbathers avoid sunburn by indicating UV level exposure. The paper wristband, similar to those given out at concerts, holds an acid-release agent that can pick up UV light. When the pH levels in the indicator reach a limit, the band will change color from yellow to pink. The team has also adapted the wristbands to reflect the different tolerance levels that people have to the sun. Someone with fairer skin will have a band that changes color quicker.
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.
