Ultraviolet Overexposure can now be detected via the world's smallest, battery-free, wearable device

New battery-free and wearable devices have been developed that can alert people to overexposure to ultraviolet (UV) rays, which is the leading cause of skin cancer. Currently, most people are unaware of the amount of UV light they are exposed to. The waterproof and robust device connects wirelessly to a smartphone and helps skin cancer survivors keep their eyes open and their minds awake.

The device, which is smaller than a credit card and tinier than an M&M, can help treat skin disorders, neonatal jaundice, seasonal affective disorder, and reduce the risk of skin cancer and sunburns.

Users can attach the device to their hats, sunglasses, or nails and record up to three separate wavelengths of light simultaneously. Even though it’s always plugged in, it never needs a recharge.

As stated in a Science Translational Medicine journal study, there are no interfaces or switches to wear out, and it is completely contained in a slender sheet of transparent plastic. Volunteers who attached a tool to their body recorded a wide range of light exposure, even when they were swimming.

Clinical phototherapy booths for treating atopic dermatitis and psoriasis, as well as neonatal intensive care unit blue light phototherapy for newborns with jaundice, were found to have therapeutic UV light monitoring. For seasonal depression, which is a type of depression that occurs at the same time each year, it demonstrated the ability to analyse white light contact.

With the approval of its patent on UV light monitoring by the US Patent and Trademark Office (USPTO), Apple’s new Watch can help prevent skin ageing, sunburn, and potentially skin cancer. It is described in Apple’s patent as a system that uses UV light sensors to track the amount of sunlight they are exposed to over time.
