South Korean researchers develop nanotech tattoos as health monitoring devices

The team at the Korea Advanced Institute of Science and Technology have created an electronic tattoo ink made of liquid metal and carbon nanotubes that effectively functions as a bioelectrode.

Researchers in South Korea are developing a new health monitoring device in the form of an e-tattoo that can automatically alert the wearer to potential health problems.

The team at the Korea Advanced Institute of Science and Technology have created an electronic tattoo ink made of liquid metal and carbon nanotubes that effectively functions as a bioelectrode.

The device could be used to send a readout of the wearer’s vital signs if connected to biosensors, including for instance an electrocardiogram.

Alongside heart rates it could be used to read glucose or lactate levels for people with diabetes or sepsis.

But the researchers plan to do away with the biosensors and design the e-tattoo as a fully self-contained device.
