Temporary scalp e-tattoos that scan brain could replace traditional EEGs forever | Scientists have developed spray-on electronic tattoos that could be a game-changer in brain monitoring.
Scientists have developed spray-on electronic tattoos that could be a game-changer in brain monitoring.
The invention, detailed in the journal Cell Biomaterials, is being heralded as a potential game-changer, not just for brain monitoring but for the growing field of brain-computer interfaces—the futuristic devices that let people control machines with their thoughts. They’ve spent years designing tiny sensors, known as electronic tattoos or e-tattoos, which stick to the skin to measure everything from heartbeats to muscle fatigue. In recent years, e-tattoos have made their way onto athletes’ chests, tracking heart rhythms, and onto people’s arms, monitoring muscle fatigue.
