A standard EEG test requires electrodes that come with pitfalls. A spray-on ink, capable of carrying electrical signals, avoids some of those.

Revolutionary e-tattoos allow scalp-printed brain monitoring, enhancing EEG comfort and future brain-computer interfaces.

Electrodes can now be printed directly onto the scalp to measure brain activity. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists ...

In a first-of-its-kind development, scientists have made a liquid ink that can be printed onto a patient's scalp to monitor ...

The ink comes in two varieties: one to form electrodes to pick up EEG signals and the other to form highly conductive interconnects that also minimize noise in the readings. First, a camera is ...

During a traditional EEG test, technicians measure the patient's scalp with rulers and pencils, marking over a dozen spots where they will glue on electrodes, which are connected to a data-collection ...
