The specialized ink could eventually replace clunky EEG wires and "potentially revolutionize" brain-computer interface devices.

Folks soon might have their brain activity scanned using a temporary tattoo, a new study suggests. This temporary scalp tattoo allowed researchers to track electrical brain activity much more easily than with conventional electrodes, researchers reported Monday in the journal Cell Biomaterials .

For the first time, scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology, presented December 2 in the journal Cell Biomaterials,

This temporary scalp tattoo allowed researchers to track electrical brain activity much more easily than with conventional electrodes, researchers reported Dec. 2 in the journal Cell Biomaterials. Electronic tattoos,

EEG recordings used in neurology could be made simpler by replacing the usual electrodes, wires and gels with a tattoo printed onto the scalp
