KIST reports first BCI chip that reads electrical and optical brain signals on one probe
Researchers at KIST's Brain Science Institute have published a peer-reviewed BCI probe in Advanced Science that combines 416 electrodes and 832 photodiodes across 13 hair-thin silicon shanks, enabling simultaneous electrical and optical brain-signal readout on a single monolithic CMOS chip. KIST claims it as a world-first at this level of density and integration. Preclinical work in live mice; not yet in primate or human. Funded by Korea's K-Moonshot Project.
