L'Oréal has developed a new battery-free wearable that detects sunlight

Beauty brand L’Oréal unveiled a new tech product at this year’s CES event that measures your UV exposure from a place that receives optimal sunlight: your thumbnail. UV Sense is a battery-free wearable electronic sensor that provides the wearer with info about their individual ultraviolet exposure levels.

Designed to be worn for up to two weeks on the thumbnail, the thin device can store up to three months of data. After two weeks, UV Sense can be reapplied to your nail with additional adhesives, which are provided in the packaging.
