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 .

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,

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,

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,

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
