My UV Patch Tracks Sun Exposure

The wearable MY UV patch from the NotCot creatives alerts the wearer when it is time to apply more sunscreen. The small adhesive patch was made with multiple layers to ensure it stays flexible and comfortable against the skin. The wearer can measure their UV exposure by holding a smartphone over the patch and triggering the app, which will display the data as a gauge running from green to red.
