OREANDA-NEWS South Korean researchers are in the process of developing e-tattoos that will act as new-age health monitoring devices, British media outlet Sky News reported. Aссording to the report, these tattoos will alert people wearing them about any potential health risks, like fluctuations in blood pressure, heart rate, or sugar levels.The medical scientists working at Korea Advanced Institute of Science and Technology (KAIST) situated in the city of Daejeon, some 140 km away from the capital Seoul, have invented an "electronic tattoo ink" after mixing carbon nanotubes with a liquid metal called gallium.

If one links the e-tattoo to an electrocardiogram (ECG) device, it can easily detect a patient's heart rate, glucose, lactate, and other vital signs.While these tattoos will have to be connected to a medical device to read a patient's vitals, the researchers ultimately plan to develop them as a fully self-contained machine that will be able to track everything on its own."In the future, what we hope to do is connect a wireless chip integrated with this ink, so that we can communicate, or we can send signal back and forth between our body to an external device," Professor Park concluded.
