Gel-Free Electrodes Read with Less Mess

Sep-19-19 Gel-free electrodes able to read brain waves through a head of hair offer a less messy way to detect brain activity.

Currently, electrodes used to detect brain activity require a conductive gel to function properly, and can still be disrupted by the person’s hair. As a simpler alternative, the team from Tsinghua University developed electrodes made up of common melamine sponge embedded with conductive nanowires. In tests, the electrodes proved as accurate as the standard version, even with no gel and when reading through a full head of hair.
