Ever wondered exactly how much your job is stressing you out? Scientists have developed a temporary forehead tattoo that ...

Ever thought so long and hard on a problem that your forehead grew hot, your brain became frazzled and your eyes grew bleary?

Analysing brainwaves could be made easier by printing a temporary tattoo onto a person’s head. Electroencephalography (EEG) is a way of measuring electrical activity in the brain via electrodes ...

the researchers can design the spots for EEG electrodes on the patient's scalp. Then, they use a digitally controlled inkjet printer to spray a thin layer of the e-tattoo ink on to the spots.

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 ...

The ink formula can also be modified to create tattoo lines onto the scalp, meaning that the wires that connect the e-tattoos to a monitor are much shorter than they would be in a regular EEG test.

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 Cell Press journal ...
