Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejon, southwest of Seoul, have developed an electronic tattoo ink made from liquid metal and carbon nanotubes that function as a bioelectrode. Connected to an electrocardiogram (ECG) device or other biosensor, it can send data about the patient’s heart rate and other vital signs such as glucose and lactate to the monitor. Reuters.
In the end, researchers tend to abandon biosensors.
“In the future, we hope to connect 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 Steve Park, professor of materials science and engineering.
Such monitors could theoretically be located anywhere, including patients’ homes.
The ink is non-invasive and consists of particles based on gallium, a soft silvery metal also used in semiconductors or thermometers. Platinum-studded carbon nanotubes help conduct electricity for durability.
“When it is applied to the skin, even after rubbing, the tattoo does not come off, which is not possible with liquid metal,” Park said.
Recall that recently in the United States was developed work to help patients with dementia.
