BERLIN — Scientists have developed a mind-controlled robotic hand that allows people with certain types of spinal injuries to perform everyday tasks such as using a fork or drinking from a cup.
The low-cost device was tested in Spain on six people with quadriplegia affecting their ability to grasp or manipulate objects.
By wearing a cap that measures electric brain activity and eye movement the users were able to send signals to a tablet computer that controlled the glove-like device attached to their hand.
Participants in the small-scale study were able to perform daily activities better with the robotic hand than without, according to results published Tuesday in the journal Science Robotics.
The principle of using brain-controlled robotic aids to assist people with quadriplegia isn’t new. But many existing systems require implants, which can cause health problems, or use wet gel to transmit signals from …
