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 .

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

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,

The analysis of brain waves with an EEG test (electroencephalography) can now be simplified thanks to printing a temporary tattoo on the scalp of the person being examined. Professors at the University of Texas at Austin have tested this method and studied several individuals.

Recording the goings-on inside the human brain is no simple task, largely because there’s a skull in the way. Over the years, we’ve developed ways of capturing brain activity using electrodes, but a team of scientists just made a big leap forward by inventing a biocompatible liquid ink that can be used to print temporary “e-tattoo” sensors
