(Natural News) Heliophiles are in for a treat. UV Sense, a recently launched sensor, can alert users when they've had too much exposure.
UV Sense is a battery-free device that can fit on a thumbnail, and it was designed to detect radiation from the sun. The sensor can change color to indicate the radiation levels of the user.
It works by measuring the length of time that a user has spent outdoors. UV Sense is less than 2 millimeters (mm) thick and 9 mm in diameter, and it reminds users to reapply sunscreen when a user scans the sensor with a smartphone.
The sensor was launched in the United States just this month, but those in the U.K. will have to wait until 2019 before they can purchase the device. Details about UV Sense's price are yet to be revealed.
UV Sense can help users strike a healthy balance between getting enough sunlight, which is crucial for vitamin D generation, and preventing skin cancers such as melanoma. (Related: Melanoma (skin cancer) found to be easily prevented with low-cost Vitamin B-3.)
Melanoma, the deadliest form of skin cancer, often spreads. More than 15,000 individuals in the U.K. are diagnosed with this cancer. It is mainly caused by overexposure to UV light.
How UV Sense tracks sun trends
When users are setting up the device for the first time, a connecting app will ask users about their skin type to determine how much sun exposure they can tolerate. UV Sense will then suggest various sun-safety products, and it can even offer general advice.
The device can be worn for at least two weeks and it can store at least three months of UV ray data. Users can then study this information to learn more about the "sun trends" in the area.
UV Sense is powered by smartphones, and it is compatible with both Android and iPhones. The sensor does not require any batteries and is activated by UV radiation.
UV Sense is manufactured by L'Oreal's Technology Incubator. Guive Balooch, L'Oreal's global vice president, said, "Armed with research and consumer insights from My UV Patch, we set out to create something that blended problem-solving technology with human-centered design."
