Brain-computer interface with artificial tactile feedback improves robotic arm control


 E-Mail
A brain-computer interface that didn t rely on vision alone but also mimics the sensation of touch dramatically improved the ability of a person with tetraplegia to manipulate objects with a brain-controlled robotic limb. The participant performed various tasks at a level comparable to able-bodied humans. Prosthetic devices controlled by brain-computer interfaces (BCIs), which measure movement-related brain activity from implanted electrodes and translate it into the conscious control of a robotic limb, have enabled some paralyzed users to regain functional movement. However, the use of BCI-controlled systems is limited. They often rely on visual cues alone and lack the critical sensory feedback from being able to feel the objects being grasped. To address this, Sharlene Flesher ....

New wireless system can restore communication and mobility in people with paralysis


New wireless system can restore communication and mobility in people with paralysis
Brain-computer interfaces (BCIs) are an emerging assistive technology, enabling people with paralysis to type on computer screens or manipulate robotic prostheses just by thinking about moving their own bodies. For years, investigational BCIs used in clinical trials have required cables to connect the sensing array in the brain to computers that decode the signals and use them to drive external devices.
Now, for the first time, BrainGate clinical trial participants with tetraplegia have demonstrated use of an intracortical wireless BCI with an external wireless transmitter. The system is capable of transmitting brain signals at single-neuron resolution and in full broadband fidelity without physically tethering the user to a decoding system. ....
