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

Researchers have developed a liquid ink that can be printed directly onto the scalp to monitor brain activity, offering a less intrusive alternative to traditional EEG setups. This ink enables the cre

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 .
