Non-invasive brain imaging is usually handled with electrodes, sticky gels, and wires: it's an ugly, uncomfortable, and ...

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

Students at the University of Texas are using 3D printers to help create e-tattoos that can help provide doctors with crucial ...

Scientists have developed a breakthrough technology: temporary electronic tattoos (or e-tattoos) that can be printed directly ...

These electronic tattoos, designed to record brain activity ... researchers at the University of Texas at Austin developed a biocompatible ink that penetrates hair to reach the scalp.

While electroencephalography (EEG) can provide a wealth of information on the electrical activity of an individual's brain, ...

The ink then dries into a thin film, known as an electronic tattoo, that is 30 micrometers thick — approximately half the width of a human hair. Like regular EEG electrodes, these e-tattoos can ...

“Our innovations in sensor design, biocompatible ink, and high-speed printing pave the way for future on-body manufacturing of electronic tattoo sensors, with broad applications both within and ...

The printer deposits the ink with sufficient speed to penetrate short hairs on the scalp. There are also short cables that link the printed e-tattoo to a small EEG recorder. Their e-tattoos ...

The e-tattoos also lasted longer ... In another round of experiments, the researchers modified the ink to additionally produce lines that can replace the wiring used in a conventional EEG.

Although it can cause ink to glow, there are concerns over ... In recent years, articles about experimental electronic tattoos with built-in lights and circuitry have fired her imagination.
