This paper evaluates low-cost polymer fiber sensors for real-time distance measurement in OPM-based biomagnetic measurements, finding high accuracy over 0-10 mm with some error beyond.

This study evaluates the reliability of spatiotemporal neuromuscular activity patterns in OPM-MMG across force levels, finding high within-subject stability in most subjects.

The paper compares complexity-based metrics from surface electromyography (sEMG) and magnetomyography (MMG) during muscle fatigue, finding that complexity captures signal organization changes not explained by amplitude or spectral features.

This study compares motor unit number estimation using optically pumped magnetometer-based magnetomyography (OPM-MMG) and surface electromyography (EMG), finding that OPM-MMG can estimate motor unit numbers contactlessly with comparable accuracy when signal-to-noise ratio is equalized.

This paper demonstrates that a portable OPM-MMG system can decode fine finger movements and recover EMG-like patterns without skin contact or a magnetically shielded room.

This study demonstrates that magnetomyography (MMG) signals can detect individual motor units non-invasively using SQUIDs and OPMs, validated by simultaneous intramuscular EMG recordings.

This study compares optically pumped magnetometers (OPM) and EMG for finger movement discrimination, finding both achieve over 89% accuracy with high agreement.

This study records magnetic and electric fields during a muscle reflex to analyze action potential dynamics and muscle structure.
