Researchers at the University of Texas at Austin have developed a temporary “e-tattoo” for the palm that can track excitement and stress using the skin’s electrical conductivity. The e-tattoo could be a reliable way for people with conditions such as anxiety or depression to track their emotions.
In a research paper published in the journal Nature Communications, the palm tattoo stayed on for 15 hours while subjects did everyday activities such as driving, eating and exercising.
Nanshu Lu, a professor at the University of Texas at Austin’s Cockrell School of Engineering, said the e-tattoo could allow patients to track stress levels without wearing a bulky medical device.
