Fascicle-Selective Bidirectional Peripheral Nerve Interface IC with 173dB FOM Noise-Shaping SAR ADCs and 1.38pJ/b Frequency-Multiplying Current-Ripple Radio Transmitter
Bibliographic record
Abstract
The peripheral nervous system (PNS) provides a conduit through which organs can communicate with the central nervous system. PNS neural interfaces have been deployed in open-loop fashion to help restore motor or sensory functions in paralyzed or amputated individuals, and also as implantable closed-loop therapeutic devices for treating chronic medical conditions related to autoimmune or metabolic disorders. Their efficacy and the scope of clinical use, however, are severely curtailed by the invasiveness of the cable, electronics and battery, and the lack of nerve fascicle selectivity and online adaptivity. We present a battery-free wireless PNS interface that features a mm-scale fascicle-selective neural interface IC with extraneural recorders and stimulators, as well as a wearable interrogator with integrated machine learning (ML) to enable adaptive neuromodulation therapy with low invasiveness.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
