World’s Smallest Wearable Warns of UV Exposure, Enables Precision Phototherapy
“The world’s smallest wearable, battery-free device has been developed by Northwestern Medicine and McCormick School of Engineering scientists to measure exposure to light across multiple wavelengths, from the ultra violet (UV) to visible and even infrared parts of the solar spectrum. It can record up to three separate wavelengths of light at one time.
The device’s underlying physics and extensions of the platform to a broad array of clinical applications were reported in a study published in Science Translational Medicine. These foundational concepts form the basis of consumer devices launched in November to alert consumers to their UVA exposure, enabling them to take action to protect their skin from sun damage…”
