Neuromorphic Airflow Sensor Inspired by Scorpions Developed for Respiratory Pattern Analysis

A new study in the *Proceedings of the National Academy of Sciences* (PNAS) details a hypersensitive neuromorphic airflow sensor, drawing inspiration from the vision-compensatory mechanoreceptors of scorpions. This biomimetic sensor, which integrates a bioinspired lever-amplification structure with a pressure-induced ionic enrichment mechanism, replicates the spike-generating behavior of neurons for efficient and omnidirectional airflow perception. It demonstrates superior sensitivity at low velocities and high accuracy (95.56%) in identifying individual human respiratory patterns, advancing brain-inspired computing and health monitoring.
