Fabrication of High‐Density Multimodal Neural Probes Based on Heterogeneously Integrated CMOS (Adv. Sci. 34/2026)

Fabrication of High-Density Multimodal Neural Probes Electrical sparks and green fluorescence converge on a single silicon shank. By heterogeneously integrating CMOS chiplets, this 13-shank neural probe simultaneously records 416-channel electrophysiology and 832-pixel calcium imaging, unlocking a new optoelectronic window into the brain. More details can be found in the Research Article by Changhyuk Lee and co-workers (DOI: 10.1002/advs.202524260).
