Researchers in South Korea are creating a brand new well being monitoring gadget within the type of an e-tattoo that may robotically alert the wearer to potential well being issues.
The group on the Korea Superior Institute of Science and Expertise have created an digital tattoo ink fabricated from liquid metallic and carbon nanotubes that successfully features as a bioelectrode.
The gadget might be used to ship a readout of the wearer’s very important indicators if related to biosensors, together with for example an electrocardiogram.
Alongside coronary heart charges it might be used to learn glucose or lactate ranges for folks with diabetes or sepsis.
However the researchers plan to put off the biosensors and design the e-tattoo as a totally self-contained gadget.
“Sooner or later, what we hope to do is join a wi-fi chip built-in with this ink, in order that we are able to talk, or we are able to ship sign backwards and forwards between our physique to an exterior gadget,” mentioned the challenge chief Professor Steve Park.
The e-tattoo ink is non-invasive and does not require a needle to be implanted beneath the pores and skin like a standard tattoo.
It’s made out of particles primarily based on gallium, a comfortable, silvery metallic additionally utilized in semiconductors and thermometers, whereas the platinum-decorated carbon nanotubes assist conduct electrical energy whereas additionally bettering the sturdiness of the tattoo itself.
“When it’s utilized to the pores and skin, even with rubbing the tattoo does not come off, which isn’t potential with simply liquid metallic,” Professor Park mentioned.
