Researchers from the University of Texas Austin and the University of California, Los Angeles developed ink that can be printed on a person's head and measure their brainwaves.

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 .

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

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
