MedicalResearch.com Interview with: Dr. Andrea M Armani PhD Fluor Early Career Chair and Associate Professor Mork Family Department of Chemical Engineering and Materials Science University of Southern California, Los Angeles, California MedicalResearch.com: What is the background for this study? Response: The “Internet of Things” (IoT) has seen an explosion in online sensor technologies, including UV sensors and monitors; for example, those from Apple and Samsung. However, they require connectivity and power, and they are integrated into delicate electronic systems that are not compatible with outdoor, athletic activities such as swimming, which is precisely when you should monitor UV exposure. Therefore, somewhat ironically, the technologies developed to meet the demands of the IoT are not ideal for cumulative UV exposure detection. Our goal was to develop a single use patch – like a smart “band-aid” – for the beach to alert users when they had been in the sun for an hour and needed to re-apply sunscreen or get out of the sun altogether. This application required a rugged system that was waterproof, bendable, and compatible with sunscreen. Additionally, the sensor readout needed to be easy to interpret. These requirements influenced our design and material selection. (more…)
