Say goodbye to messy gels and tangled wires because scientists in Austin, Texas are taking brain monitoring into the future with spray-on e-tattoos. For nearly a century, electroencephalogram or EGs have helped scientists and doctors measure the electric pulses that fire through our brains, diagnosing everything from epilepsy to traumatic brain injuries.

But EEGs, clunky and outdated, are getting a sleek upgrade thanks to a conductive liquid ink that creates ultra-thin tattoos directly on your scalp. Scientists have created a liquid ink that can be sprayed directly onto a person’s scalp, forming an ultra-thin electronic tattoo. This “tattoo” EEG listens to the brain beneath it.
