Researchers developing health-monitoring e-tattoo

Stories of people embedding digital devices into their bodies are becoming increasingly common; with these digital implants capable of everything from aiding mobility to paying for products, unlocking doors and storing data. A team of researchers from the Korea Advanced Institute of Science and Technology have taken a similar concept and applied it to the world of health monitoring – though their method is a little less invasive.

Using liquid metal and carbon nanotubes, the team created an electronic ink tattoo that does not require a needle to be applied.

The e-tattoo monitors physiological symptoms of the user, tracking vital signs such as blood sugar levels and heart rate and automatically alerting the wearer to any perceived anomalies. Data on a user’s vitals over time can also be connected to biosensors and used to track patterns or problems.
