Mind Over Mechanics

In a jaw-dropping feat of engineering, electronics turn a person's thoughts into commands for a robot. Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring. The technology may someday allow people robbed of speech and mobility by neurodegenerative diseases to regain function by controlling artificial limbs, wheelchairs, or other devices. And it's completely noninvasive: Brain waves (EEG) are picked up by the electrodes of an EEG cap on the scalp, not a chip implanted in the brain. A report on the technology has been published in the Journal of Neural Engineering. Read full article at the University of Minnesota.
