# UV Exposure-Detecting Wristbands This Paper Wristband Lets You Know When to Head Indoors By Michael Hemsworth | Published 2018-10-06 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/paper-wristband References: [newatlas](https://newatlas.com/sun-exposure-wristband/56662/) & [rmit.edu.au](https://www.rmit.edu.au/news/all-news/2018/sep/wearable-uv-sensors) A little bit of sun exposure is healthy and essential but too much can lead to skin damage and cancer, so this paper wristband has been developed as a cost-effective solutions to help wearers know when they should seek coverage. Developed by a team of researchers at the [RMIT University](https://www.trendhunter.com/trends/rmit-futures-series) in Australia and the [University of Granada](https://www.trendhunter.com/trends/skinworn-sensor) in Spain, the wristband features specialized phosphomolybdic ink on the exposed portion. This ink will change from colorless to blue once it has been exposed to [UV light](https://www.trendhunter.com/trends/selfrepairing-uv-tech) and has been paired with transparent film layers over some portions to make it harder for rays to permeate. This helps wearers of the paper wristband to quickly identify when they have gotten their limit of sun to remind them when it's time to head indoors.
