Researchers at Brown University and participants in a clinical trial of the BrainGate brain-computer interface have demonstrated use of an intracortical wireless version of the interface with an external wireless transmitter.

Two clinical trial participants with paralysis used the BrainGate system with a wireless transmitter to point, click, and type on a standard tablet computer. The work is described in "Home Use of a Percutaneous Wireless Intracortical Brain-Computer Interface by Individuals With Tetraplegia" published in IEEE Transactions on Biomedical Engineering.

"We've demonstrated that this wireless system is functionally equivalent to the wired systems that have been the gold standard in BCI performance for years," says John Simeral at Brown and a member of the BrainGate research consortium.
