Many people who soak up memories like to remember the good old days when sunlight was softer and less aggressive to skin. countries like australiaover the past decades more UV rays Between 6% and 9% annually. Similarly, skin cancer, one of her most dangerous and aggressive, is becoming more and more prevalent. There are many factors contributing to this situation. More sunny days, thinning ozone in southern latitudes while it is growing in Antarctica, the solar cycle and, of course, the never-ending quest for the perfect tan. Therefore, any measures taken to assess and control sun exposure are most welcome. The latest one is smart bracelet UV exposure can be measured.
this innovative device Developed in Australia, a country with one of the highest rates of skin cancer. In collaboration with a team from the University of Granada (Spain), researchers from the University of RMIT (Australia) have developed a simple and cost-effective solution for detecting the amount of UV radiation by using polyoxometalate liquids as reactants. is created. These disposable and recyclable bracelets are made of paper and feature four faces ranging from a smiley to a frown that are revealed at varying levels of UV exposure ranging from 25% to 100% of healthy total. It features letters.
Vitamin D problem
Surprisingly, the first idea for this was technology project It wasn’t because of skin cancer prevention, but because of the vitamin D deficiency that one of the researchers, Professor Vipul Bansal, who wanted to increase sun exposure within a safe range, suffered. In fact, each skin type requires a certain amount of UV light to metabolize vitamin D, depending on the level of pigmentation. So the final device comes in his six different models covering the full range of human skin tones.Furthermore, this New technology It is especially useful for individuals suffering from diseases like lupus.Lupus alters the ability to metabolize vitamin D through diet, but also suffers from photosensitivity.
beyond human skin
For now, the main uses for these are smart bracelet Especially for protecting children’s skin, this technology could have other interesting applications. For example, using this technology to implement labels can protect food in a similar way. A new generation of smart ink The expiration date can be displayed in real time.
