It could someday be an important tool in the fight against skin cancer.

Researchers at Northwestern University may have a device that could warn you when you're getting sunburned.

"The world's smallest wearable device" is feather-light, waterproof, battery-free, wafer-thin, and is about the size of a Tic-Tac.

Users can place the sensor onto a fingernail, clothing, even sunglasses. 

The device detects UVA and UVB rays and sends data to an app on your phone.

Professor John Rogers says users can personalize the app with skin type, family history, and location.

"It will tell you here's how much time you have to remain in the sun with those sets of conditions, and with the data coming from this device, before you'll get burned," Rogers said.

Users will see an hourglass graphic to count down the minutes before a possible sunburn.

The wearable device is in the final steps of manufacturing and is set to hit the market in 2019.
