Brain-Computer Interfaces (BCI)
High-bandwidth bidirectional neural interfaces.
Form Factors
BCIs vary from non-penetrating ECoG grids (high SNR, low tissue damage) to penetrating microelectrode arrays (single-unit resolution, high gliosis) and endovascular stents (no craniotomy required).

FAQ
How is data extracted?
Via transcutaneous RF links or percutaneous pedestals depending on the device phase.
