Funding goal: $10,000
Total pledged: $49+
Deadline: May 12
SolAlert is a UV-sensitive, color changing sticker created by Propper Manufacturing Co.
The sticker gradually changes from pink to pale yellow the longer the user is exposed to the sun. The sticker lets a user know when they’ve reached the daily 1 Standard Erythemal Dose, which is the standard measurement for ambient ultraviolet rays. When the sticker turns yellow, the user is alerted that they’ve reached the Standard Erythemal Dose threshold.
Scientists created this sticker by first developing a UV-responsive ink. They developed an end point for the color change of 1 Standard Erythemal Dose, which is about the amount of sun known to cause the early stages of sunburn. After several months of working on the ink, the scientists created a formula and printed it on adhesive dots that can be easily applied and removed from clothing, bags, hats and other fabric items.
