Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon city have used this ink to create a personalized tattoo device that functions as a bioelectrode, Reuters reports.
After application, such a tattoo will automatically warn a person about possible health problems. To do this, it is connected to an electrocardiogram (ECG) device or other biosensor.
The device will send data on the patient's heart rate and other vital signs such as blood glucose and blood lactate to the monitor. health can theoretically be located anywhere, including patients' homes.
It is the ink that is non-invasive and consists of particles based on gallium – a soft silvery metal that is also used in semiconductors and thermometers.
Platinum-coated carbon nanotubes help conduct electricity and ensure the durability of the device. In their future developments, scientists want to abandon biosensors altogether.
“In the future, we hope to have a wireless chip integrated with this ink so that we can communicate or transmit a signal between our body and back to an external device,” – said project leader Professor Steve Park.
