A group of scientists say they have developed a mind-controlled robotic hand that will allow people with certain types of spinal injuries to perform tasks such as using a fork or drinking from a cup. People who participated in the study wore a glove-like device on a hand and a cap that measures electric brain activity and eye movement. The cap sends signals to a tablet computer that controls the hand device. Results from a small study were published in the journal Science Robotics. Other robotic devices have been tested in recent years, but many required surgical implants or wet gel that transmits signals from the scalp to the electrodes.
