Colour-change wristbands can track your sun exposure
Wristband can track sun exposure

A new single-use, disposable wristband that can be printed using a UV active ink that changes colour when exposed to different types of UV rays has been developed by RMIT researchers.

When the wristband is exposed to sunlight, the sensor lights up with four smiley faces. The wearer is warned it is time to get out of the sun when the fourth sad smiley appears, as they have reached their maximum allowed daily UV dose.

While we all need some sun exposure to ensure we maintain healthy levels of Vitamin D, excessive exposure can be detrimental, causing sunburn, skin cancer and premature signs of ageing.

Professor Vipul Bansal from RMIT University used his personal struggle with Vitamin D deficiency to develop the sensors which can be printed onto any paper-like surface such as wristbands, headbands and stickers. The sensors come in six variations to reflect skin tonality. The colour produced by the sensor indicates when 25 per cent, 50 per cent, 75 per cent and 100 per cent of the daily recommended UV exposure has been reached.

Would you use this product to monitor your exposure to harmful UV rays? Are you cautious about how much time you spend in the sun? Do you know if you are getting enough vitamin D?

    Another gimmick, I would not trust it, I think it is better to just stay out of the hot sun, even using sunscreen is not safe which have chemicals that stop the Vitamin D and are linked to cancers. Better off covering up and knowing yourself when you have had enough sun, you can feel it and see it on your skin.

    I'd give it a go (subject to price, of course). Sunscreens don't work for me, so nothing to lose.
