Abstract
This article presents a bioinspired, event-driven
neuromorphic sensing system (NSS) capable of performing
on-chip feature extraction and “se nd-on-delta” pulse-based trans-
mission, targeting peripheral nerve neural recording applications.
The proposed NSS employs event-based sampling which, by lever-
aging the sparse nature of electroneurogram (ENG) signals,
achieves a data compression ratio of >125×, while maintaining a
low normalized rms error (NRMSE) of 4% after reconstruction.
The proposed
