"New Sensor Allows Mind-Control of Robots via Brain Waves"
Researchers have designed a dry sensor that can measure brain activity and may enable mind control of robotic systems. The 3D-patterned structure doesn't rely on sticky conductive gels and can measure the brain's electrical activity amidst hair and the bumps and curves of the head. The team created several 3D graphene-coated structures with different shapes and patterns, and a hexagonal pattern worked the best on the curvy, hairy surface of the occipital region. The electrodes could detect visual cues and work with a computer to interpret the signals into commands that controlled the motion of a four-legged robot, completely hands-free.
