South Korean scientists are working on a health device in the form of a tattoo that could alert users to possible health problems. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an electronic ink made of liquid metal and very small tubes of carbon, or carbon nanotubes. The ink works by creating something like an electric circuit on the skin. When the tattoo is connected to an electrocardiogram device or other biosensor, it can send a patient’s heart rate and other important health signs to a monitor. Steve Park is the leader of the research project. He said, 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. External device monitors could be located anywhere, including in patients’ homes. The electronic ink is much more comfortable for the user than existing biosensors, Park said. He called it biocompatible, meaning it does not hurt living tissue. Park added that the ink can be removed with soap. The ink is non-invasive and made from particles based on gallium, a soft, silvery metal also used in semiconductors and in thermometers. The carbon nanotubes help conduct electricity and keep the tattoo on the skin. Park said, When it is applied to the skin, even with rubbing the tattoo doesn't come off, which is not possible with just liquid metal.
