Graphene-based wearables for health monitoring, food inspection and night vision…hmmm

Scientists have developed dozens of new graphene-based prototypes. These technologies aim to turn mobile phones into life saving devices.

The first of ICFO’s devices on display will allow customers to monitor their level of exposure to sunlight through a UV sensor. Designed as a flexible, transparent and 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’s fitness band is being developed to measure heart rate, hydration, oxygen saturation, breathing rate and temperature, while monitoring the user when he or she is exercising, for example. However, the fitness band does more than simply measure physical activity.

Consider the following scenario. A person is trekking in the remote amazon jungle with limited access to water. By measuring the skin hydration of their body with ICFO’s fitness band, the user can optimize water intake, preventing any sort of dehydration. Similarly, an explorer hiking to the peak of mount Everest could use the band to accurately monitor oxygen saturation in blood. The high altitude can severely effect oxygen saturation in the body. Using the band, the hiker could monitor these levels and emit a warning if oxygen saturation in the blood decreases drastically below a certain level.
