South Korea develops nanotech tattoo as health monitoring device

 South Koreans may before long have the option to convey a gadget inside their own bodies as a custom tattoo that naturally makes them aware of potential medical conditions, assuming that a science group's undertaking proves to be fruitful.

Specialists at the Korea Advanced Institute of Science and Technology (KAIST) in the city of Daejeon southwest of Seoul have fostered an electronic tattoo ink made of fluid metal and carbon nanotubes that capabilities as a bioelectrode.

Connected to an electrocardiogram (ECG) gadget or other biosensor, it can send a readout of a patient's pulse and other essential signs such glucose and lactate to a screen.

The analysts in the end expect to have the option to abstain from biosensors.

"Later on, what we desire to do is interface a remote chip incorporated with this ink, so we can impart, or we can convey message to and fro between our body to an outer gadget," said project pioneer Steve Park, a materials science and designing teacher.

Such screens could in principle be found anyplace, remembering for patients' homes.

The ink is painless and produced using particles in light of gallium, a delicate, gleaming metal likewise utilized in semiconductors or in thermometers. Platinum-adorned carbon nanotubes assist with leading power while giving strength.

"At the point when it is applied to the skin, even with scouring the tattoo doesn't fall off, which is unimaginable with simply fluid metal," Park said.
