Head tattoos are usually a last frontier reserved for true ink addicts, but they could help make it a whole lot easier to record someone's brain activity.

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

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 .

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

Scientists have developed a new technology that can measure brain waves using electronic, temporary tattoos. The researchers say the method could act as a quicker and more convenient way to monitor brain activity and diagnose neurological conditions,
