Brain-computer interfaces without the mess

It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes. Even better, the devices work through a full head of hair. The researchers report the flexible electrodes, which could someday

Electrode shape improves neurostimulation for small targets

A cross-like shape helps the electrodes of implantable neurostimulation devices to deliver more charge to specific areas of the nervous system, possibly prolonging device life span, says research published in March in Scientific Reports. The shape, called “fractal,” would be particularly useful for stimulating smaller areas, such as deep brain structures or the retina, since
