Researchers from non-profit outfit ICFO have developed new graphene-based technologies for health monitoring, food inspection and night vision. The first innovation is a fitness band that keeps track of the wearer’s physical activity. Most importantly, the band is also able to monitor the physical well-being of the wearer.

The band can measure skin hydration to optimize the wearer’s water intake to prevention any dehydration, it’s also capable of monitoring oxygen saturation in the bloodstream to guard against oxygen deprivation at high altitudes. It can advise the wearer to seek shelter from the sun as it can monitor the amount of ultraviolet rays the wearer has been exposed to, especially when the threshold level is reached.

The researchers will also showcase two light-based graphene technologies. They include the “world’s smallest single pixel spectrometer and a graphene-enabled hyperspectral image sensor.” The first technology can be applied to food monitoring where a low-cost portable spectrometer can identify harmful substances within food products. It can also be used for detection of counterfeit drugs.

The second technology can be applied to a smartphone camera that features a graphene-based camera sensor that is made up of thousands of photodetectors and it’s highly sensitive to UV and infrared light. It can be used for night-vision imagery as well as detection of particular substances within products. This demonstrates the feasibility of integration of graphene with CMOS to enable a wide range of optoelectronic applications.

According to the researchers, by enabling spectroscopy in such small dimensions, consumers can now be equipped with high-specialized tools that were once limited to the confines of research laboratories.
