Researchers in South Korea are creating a brand new well being monitoring system within the type of an digital tattoo that may robotically alert the wearer to potential well being issues.
The analysis workforce at Korea Superior Institute of Science and Expertise has created an digital tattoo ink product of liquid metallic and carbon nanotubes that successfully features as a bioelectrode.
The system could possibly be used to learn the wearer’s vitals if linked to biosensors, together with an electrocardiogram, for instance.
Together with coronary heart price, it may be used to learn glucose or lactate ranges for folks with diabetes or sepsis.
However the researchers plan to remove the biosensors and design the digital tattoo as a totally standalone system.
“Sooner or later, what we hope to do is join a wi-fi chip that integrates this ink, in order that we are able to talk or we are able to ship indicators forwards and backwards between our physique and an exterior system. outdoors,” mentioned Professor Steve Park, challenge chief. .
The e-tattoo ink is non-invasive and doesn’t require a needle to be implanted beneath the pores and skin like conventional tattoos.
It’s created from particles based mostly on gallium, a comfortable, silvery metallic additionally utilized in semiconductors and thermometers, whereas platinum-decorated carbon nanotubes assist conduct electrical energy whereas enhancing the sturdiness of the metallic. tattoo.
“When it’s utilized to the pores and skin, even when rubbed, the tattoo doesn’t come off, which isn’t doable with liquid metallic solely,” Professor Park mentioned.
