A group from the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon has developed an electronic tattoo ink that functions as a bioelectrode and is made of liquid metal and carbon nanotubes.
The gadget may provide a readout of a patient’s vital signs and heart rate to a monitor after it is linked to an electrocardiogram (ECG) device or other biosensors. The scientists want to eventually be able to do without biosensors.
According to researchers, the monitors may be placed everywhere, including in patients’ homes. Gallium, a soft metal used in thermometers, is the basis for the non-invasive ink, which is formed of particles based on it. The ink is strengthened and conducts electricity thanks to the nanotubes.
When it is put to the skin, the tattoo remains after vigorous rubbing, which is impossible with merely liquid metal, according to Park.
According to a recent survey, approximately 40% of people in the U.S. already use digital healthcare choices, whether they be for counseling, telemedicine, or both.
