Color-changing wearable tracks sun exposure

Researchers have developed a wearable patch that warns users by changing colors when they’ve had too much sun exposure.

Striking a balance between too much and too little sun exposure can be challenging, according to researchers at the University of Southern California Viterbi School of Engineering. Too much sun can cause melanoma, which kills 1 person every 52 minutes in the U.S., according to the Skin Cancer Foundation. But sun exposure stimulates the production of Vitamin D, which is vital for good bone health.

The millimeter-thick patch notifies users by changing color depending on total UV exposure. The sensor turns orange when the user has reached the World Health Organization’s recommended dose of Vitamin D.
