First Human Use of Wireless Brain-computer Interface by Angela Mohan on April 5, 2021 at 7:27 PM Tetraplegia patients have demonstrated the use of an intracortical wireless BCIs with an external wireless transmitter. These BCIs enable patients 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. 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.
