Scaling Neural Interface: Towards High-Density and Multimodal Integrated Bioelectronic Systems

Recent advances in neuroscience demand hardware platforms capable of recording and modulating neural activity at increasingly large scales. In this seminar, I will present our work on integrated circuits for high-density neural recording and minimally invasive stimulation. The talk will highlight a 5,376-channel neural recording ASIC enabling simultaneous full-band acquisition with compact stacked packaging and high-speed data streaming. I will also present two magnetic-field-based stimulation approaches: one leveraging ferromagnetic resonance of magnetic nanoparticles for efficient localized heating, and another using a miniaturized magnetic coil for energy-efficient neural excitation. These systems demonstrate scalable and minimally invasive strategies for neuromodulation. Finally, I will briefly discuss the broader vision of integrated bioelectronic platforms that extend neural interfaces beyond conventional electrical modalities.
