This novel technology looks like a sci-fi device. But it's real.
, the technology has tremendous potential in industries such as sophisticated manufacturing, aerospace, and healthcare, such as allowing persons with disabilities to control wheelchairs or operate prosthetics.Electroencephalography is a technique doctors use to monitor electrical signals from the brain by implanting or placing specialized electrodes on the surface of the head.
Researchers have been working on "dry" sensors that do not require gels as an alternative, but none have performed as well as the gold-standard wet kind. Although The researchers produced numerous 3D graphene-coated structures with varying shapes and patterns, each approximately 10 m thick.performed the best of the designs examined on the curved, hairy surface of the occipital region — the location at the base of the head where the brain's visual cortex is located. Eight of these sensors were combined into an elastic headband that kept them against the back of the head.
