Electronic face tattoo knows when you're getting bored

Breakthroughs, discoveries, and DIY tips sent every weekday. Face tattoos, typically reserved for rappers and rockers, could one day be used to make sure everyday office workers aren't overexerting themselves. This week, researchers from the University of Texas unveiled a new, removable, sticker-like electronic face wearable that uses electroencephalography (EEG) and electrooculography (EOG) to constantly monitor changes in the wearer's mental strain as they complete tasks. In theory, the e-tattoo could ensure air traffic controllers or other workers in similarly high-stress environments stay in the "Goldilocks zone" of mental exertion: not so much that it causes errors, but not so little that it leads to boredom and distraction. And unlike regular face tats, these can come off at the end of the day.
