While companies like Neuralink popularize assistive BCIs for controlling external devices, a different segment is focused on therapeutic applications. Companies like InBrain aim not to control computers but to use high-resolution interfaces to directly heal or modulate neural circuits for treating diseases.
Graphene's combination of extreme flexibility, superior conductivity, and biocompatibility directly addresses the failures of rigid metal electrodes. This allows for high-resolution BCIs that conform to the brain's surface, enabling more precise and stable neural stimulation and recording for long-term treatment.
For decades, the efficacy of brain-computer interfaces (BCIs) has been hampered by metal electrodes that are too rigid for soft brain tissue. This mechanical mismatch causes chronic inflammation, scar tissue, and signal degradation, creating a significant obstacle for long-term therapeutic implants.
