Financial Times profiled the University of Chicago’s neuroprosthetic system using Blackrock implants to restore sensation in individuals with paralysis.
Advances in brain-computer interfaces enable paralysed users to feel objects in a realistic way via a robotic limb.
Scientists have for the first time given a realistic sense of touch to people operating a robotic hand via signals sent from their brain, marking the latest advance in neurotechnology research to help overcome disabilities. The University of Chicago study, published in Science on Thursday, worked over several years with volunteers paralysed by spinal cord injuries. They had tiny electrodes implanted in the brain’s sensory and motor regions that control sensations and movements in the arm and hand. The subjects learned not only to grasp objects by driving a bionic limb with their thoughts — a feat achieved in previous research — but also to feel edges, shapes and movements. Such rich two-way communication between the robotic hand and brain raises hopes that intuitive systems could improve the lives of millions of disabled people.
