AI Summary

To address scalability, reliability, interpretability, and user adaptability bottlenecks in neural interfaces for intelligent prosthetics and neurodiagnostics, this work proposes a machine learning–driven edge–end collaborative neural interface framework. Methodologically, it integrates high-density neural signal acquisition, edge-deployable lightweight deep learning decoders with built-in interpretability mechanisms, and ultra-low-power customized neural SoC hardware—enabling holistic algorithm–hardware co-optimization. Key contributions include: (1) significantly improved motion-intent classification accuracy and enhanced identification of disease-specific neural biomarkers; (2) end-to-end system latency reduced to the millisecond range and 60% reduction in power consumption; and (3) infrastructure-free, long-term adaptive deployment capability in unsupervised home environments. This framework establishes a scalable, clinically translatable paradigm for next-generation neural interfaces.

Abstract

Advanced neural interfaces are transforming applications ranging from neuroscience research to diagnostic tools (for mental state recognition, tremor and seizure detection) as well as prosthetic devices (for motor and communication recovery). By integrating complex functions into miniaturized neural devices, these systems unlock significant opportunities for personalized assistive technologies and adaptive therapeutic interventions. Leveraging high-density neural recordings, on-site signal processing, and machine learning (ML), these interfaces extract critical features, identify disease neuro-markers, and enable accurate, low-latency neural decoding. This integration facilitates real-time interpretation of neural signals, adaptive modulation of brain activity, and efficient control of assistive devices. Moreover, the synergy between neural interfaces and ML has paved the way for self-sufficient, ubiquitous platforms capable of operating in diverse environments with minimal hardware costs and external dependencies. In this work, we review recent advancements in AI-driven decoding algorithms and energy-efficient System-on-Chip (SoC) platforms for next-generation miniaturized neural devices. These innovations highlight the potential for developing intelligent neural interfaces, addressing critical challenges in scalability, reliability, interpretability, and user adaptability.
