It's a temporary tattoo more advanced than anything you'll ever find in Cracker Jack box: Researchers have developed thin, flexible electrode that can measure electrical signals on the skin after being applied like tattoo. The technology was designed to make long-term, stable recordings of muscle activity without inconveniencing person wearing it. "The key innovation is making electrodes extremely thin," study leader Yael Hanein, an associate professor engineering at Tel Aviv University Israel, told Live Science email. "This feature solved all challenges regular electrodes." [Bionic Humans: Top 10 Technologies] electronic tattoos could variety applications, including map emotions based facial expressions, neuro degenerative diseases and control prostheses, researchers said statement. Hanein added her lab already exploring potential ways be used for psychological evaluations as diagnostic tool Parkinson's disease, neurological disorder cause tremors, stiffness coordination problems. "electric tattoo" made up three main parts: carbon electrode, adhesive surface fastens polymer coating conduct electricity, major benefits include long-term stability comfort, addition, simple quick application skin," she said. However, "there still work done data capturing analysis," added. new represents exciting development, Lisa Feldman Barrett, psychologist who studies emotion Northeastern but wasn't involved with study. "Right now, we apply sensors people's gel, it's messy," Barrett Science. Even though anticipates using this sort own lab, there are some things simply won't able measure. "There no technological advances will let you read someone's face. Emotions just don't that," According cross-cultural demonstrate aren't universally linked certain context crucial when guess feelings those around us. "Emotions detected — they're perceived,"
