For several years, our exposition to UV rays has increased and scientists noticed an upward trend in risks of developing skin cancers.
Although protections exist to avoid this issue, we can’t feel the UV rays, or too late.
For that reason, we developed a wearable UV-sensitive badge so that people can be warned anytime and anywhere of their UV exposition. The badge turns red when exposed to UVs.
This badge contains a liquid cell culture. The cells are engineered so that they can produce a red fluorescent protein. They only produce it when the badge is exposed to UV rays, thanks to a photocaged amino acid.
