Graphene-Based Wearables on Display at Mobile World Congress 2019

A new device from the Institute of Photonic Sciences (ICFO) allows users to monitor their level of exposure to sunlight through a UV sensor. Designed as a flexible, transparent, disposable patch, it connects to a mobile device and alerts the user once he or she has reached a defined threshold of sun exposure. Using the same core technology as the UV patch, ICFO is developing a fitness band to measure heart rate, hydration, oxygen saturation, breathing rate, and temperature. ICFO exhibited these wearables at the Mobile World Congress (MWC) 2019, Feb. 25-28, 2019, in Barcelona.
