South Korean scientists are working on a health device in the form of a tattoo that can alert users to possible health problems.
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an electronic ink consisting of liquid metal and a very small tube made of carbon or carbon nanotubes. The ink works by creating something like an electrical circuit on the skin.
if the tattoo is attached to an electrocardiogram machine or similar biosensor, It can send a patient’s heart rate and other important health signals. Monitoring.
Steve Park is the leader of the research project. He added: “In the future we hope to be able to connect a wireless chip Integrated with this ink so we can communicate, or we can send signals back and forth between our bodies external Device.”
Monitors for external devices can be placed anywhere, including in patients’ homes.

According to Park, electronic ink is more convenient for the user than existing biosensors. He called it “biocompatible,” meaning it doesn’t harm living tissue.
Park said the ink could be removed with soap.
The ink is non-aggressive and consists of particles based on gallium, a soft, silvery metal also used in semiconductors and thermometers. Carbon nanotubes help conduct electricity and maintain tattoos on the skin.
Park said, “If it Applicable As for the skin, even rubbing the tattoo will not come off, which is just not possible with liquid metal.”
