    The new technology represents an exciting development, said Lisa Feldman Barrett, a psychologist who studies emotion at Northeastern University but wasn’t involved with the new study.

    “Right now, we apply sensors to people’s skin with gel, and it’s messy,” Barrett told Live Science.

    Even though she anticipates using this sort of technology in her own lab, Barrett said there are some things an electrode simply won’t be able to measure. “There are no technological advances of this sort that will ever let you read emotions in someone’s face. Emotions just don’t work like that,” she said.

    According to Barrett, cross-cultural studies demonstrate that emotions aren’t universally linked to certain facial expressions, and context is crucial when we guess the feelings of those around us. “Emotions aren’t detected — they’re perceived,” she said.
