High-Bandwidth Brain-Computer Interfaces (BCIs) are advanced neural interfaces that enable direct communication between the human brain and external devices, with a focus on achieving high data throughput from large populations of neurons.
They address the challenge of restoring movement and communication capabilities for individuals with severe paralysis or neurological disorders by providing a direct neural pathway to external devices.
These interfaces consist of implanted electrode arrays that capture neuronal activity. On-board processing chips decode this activity in real time to interpret intended movements or commands, which are then transmitted wirelessly to control various devices such as cursors, robotic limbs, or speech synthesizers.
Manufactured using advanced microfabrication techniques to create thin, flexible electrode arrays. The on-board chips are fabricated through semiconductor processes similar to those used in other electronic devices.
The process involves designing and fabricating the electrode arrays and processing chips, integrating them into a biocompatible package, and then testing their functionality both in vitro and in vivo before implantation.
