Current electrochemical theory does not adequately describe realistic platinum electrodes. Scientists at Leiden University have now, for the first time, mapped the influence of imperfect platinum ...

University of Toronto researchers have developed a flexible, biodegradable electrode capable of stimulating neural precursor cells (NPCs) in the brain—a device capable of delivering targeted ...

Brain–computer interfaces are technologies that enable direct communication between brain activity and external devices, enabling researchers to monitor and interpret brain signals in real time. These ...

Measuring brain waves could become easier with electrodes and wires that researchers can paint on the scalp through parted hair using a paintbrush. Made with a conductive polymer ink, the ...

It’s an unusual aesthetic, but it works: Spray-on tattoos that dot the head can collect brain activity without the consternation caused by typical tests. The electronic tattoos, described December 2 ...
