NeuroBus - Architecture for an Ultra-Flexible Neural Interface

Ioana-Georgiana Vasilas, Prof. Thomas Stieglitz, Prof. Ilka Diester, and Ahmed Adzemovic celebrate their joint paper! (missing on the foto: Calogero Gueli)

Interdisciplinarity pays off!

The paper introduces NeuroBus, an implant concept, featuring a system architecture with tiny ASICs on a flexible substrate. The bus-like structure allows short, customizable connections with low wiring effort. The small size and flexibility of ASICs enable adaptation to the brain's curvature, ensuring high biocompatibility. The study outlines architecture, building blocks, and post-CMOS processes for NeuroBus, presenting a direct digitizing neural recorder and a polyimide-based ECoG brain interface. Validation in a rodent model confirms the joint capability of the recording front-end and thin-film electrode array.

Among the authors consortium are our spreakers Prof. Stieglitz and an Prof. Diester together with their PhD students Ioana-Georgiana Vasilas, Ahmed Adzemovic, and Calogero Gueli.
