NeuroLiaison: Interceptação Automatizada de NCSE, Rastreamento de Burst-Suppression e Complacência Intracraniana

A NeuroLiaison projeta interfaces neurais periféricas bidirecionais (PNIs), decodificando a intenção motora por eletroneurograma de alta densidade (ENG) para comandar próteses biônicas robóticas enquanto estimula aferências sensoriais com pulsos biomiméticos de microssegundos para restaurar tato e propriocepção naturais.

NeuroLiaison Closed-Loop Bidirectional Neural Interface Architecture

ENG motor intent decoding, biomimetic sensory stimulation, and charge-balanced ASIC

Central System: Neural Interface Controller - Bidirectional ENG/Sensory ASIC

Clinical IoMT Nodes

  • Transversal Intrafascicular Electrode (TIME)
  • Low-Noise Neural Recording Front-End
  • Real-Time Motor Intent Decoder
  • Biomimetic Sensory Stimulation Engine
  • Bionic Limb / Robotic Actuator

Architectural Layers & Regulatory Standards

  • Intraneural Micro-Electrode Interface (TIME Array / Longitudinal Intrafascicular Electrodes (LIFE)): Interfacing directly with nerve axons inside individual peripheral fascicles (median, ulnar, and radial nerves).
  • Neural Signal Conditioning & Artifact Blanking (Dynamic Artifact Suppression / High-CMRR Bio-Amps): Recording microvolt-level neural action potentials while suppressing stimulation artifacts and muscle EMG cross-talk.
  • Intent Decoding & Neural Prosthetic Telemetry (Kalman Filter / Recurrent Neural Networks): Translating decoded firing rates into smooth, proportional prosthetic joint movements in real time.
  • Biomimetic Afferent Sensory Stimulation (Charge-Balanced Biphasic Current Stimulation): Encoding fingertip pressure sensor data into patterned electrical stimulation delivered to sensory nerve fibers.

Key Metrics: < 40 ms (Closed-Loop Sensorimotor Latency) | < 1 µV RMS (ENG Recording Amplifier Noise) | 100% (Charge-Balanced Current Injection) | 10 Years (Implantable Silicone Encapsulation Lifespan)
