South Korea develops nanotech tattoo as health monitoring device

Published

on

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, Reuters reported Tuesday. 

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.

Hooked up to an electrocardiogram (ECG) device or other biosensor, it can send a readout of a patient’s heart rate and other vital signs such glucose and lactate to a monitor.

The researchers eventually aim to be able to dispense with biosensors.

“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,” said project leader Steve Park, a materials science and engineering professor.

Such monitors could in theory be located anywhere, including in patients’ homes.

The ink is non-invasive and made from particles based on gallium, a soft, silvery metal also used in semiconductors or in thermometers. Platinum-decorated carbon nanotubes help conduct electricity while providing durability.

“When it is applied to the skin, even with rubbing the tattoo doesn’t come off, which is not possible with just liquid metal,” Park said.

Afghanistan is set to launch a new nationwide polio vaccination campaign on Monday, November 2, as health authorities continue efforts to eradicate the disease, following the vaccination of 12.7 million children across the country.

Afghanistan’s Polio-Free Initiative announced that the campaign will begin nationwide on Monday, while vaccination activities in the southern zone will start a day later, on Tuesday, November 3.

Meanwhile, the United Nations Children’s Fund (UNICEF) said that 12.7 million children in Afghanistan have been vaccinated against polio through ongoing immunization campaigns.

The UN agency noted that despite progress in vaccination coverage, efforts to completely eliminate polio in Afghanistan are continuing.

Polio is a highly infectious viral disease that mainly affects children under the age of five and can cause permanent paralysis.

Health organizations have urged families to cooperate with vaccination teams and ensure that all eligible children receive the required vaccine doses to protect them against the disease.

Afghanistan Free Polio has urged parents and caregivers to vaccinate their children against polio, warning of the continued need for vaccination efforts as the country marks World Polio Day on October 24.

In a message issued on Saturday, the organization called on families to ensure their children receive polio vaccines, stressing that every child has the right to grow up free from the disease.

The organization also emphasized the role of families and communities in preventing the spread of the virus and achieving a polio-free Afghanistan.

According to a previous report by the World Health Organization (WHO), six new polio cases had been recorded in Afghanistan, bringing the total number of cases reported since the beginning of 2026 to 42.

Afghanistan and Pakistan remain the only countries where polio has not been eradicated.

World Polio Day is observed annually on October 24 to raise awareness and strengthen global efforts to eliminate the disease.

Health authorities and public health organizations continue to stress that vaccination and community participation are essential to protecting children and preventing further transmission of the virus.
