South Koreans may soon be able to carry a device inside their own bodies in the form of a bespoke tattoo that automatically alerts them to potential health problems, if a science team's project bears fruit.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in the city of Daejeon southwest of Seoul have developed an electronic tattoo ink made of liquid metal and carbon nanotubes that functions as a bioelectrode.
