Monolithic 3D Nanoelectrode Arrays on CMOS Circuitry for Scalable, High‐Resolution Neural Recording (Small 22/2026)

Neural Recording A CMOS-integrated platform featuring 26,400 three-dimensional nanoelectrodes enables high-resolution extracellular recordings via intimate cell-electrode coupling at the subcellular neuritic scale. Wafer-scale, low-temperature monolithic integration preserves CMOS circuit performance. The system enhances spike amplitudes and signal-to-noise ratios while revealing diverse neuronal waveform morphologies, including putative dendritic signals.
