    Area of Science:

    • Biomedical Engineering
    • Neuroscience
    • Biometrics

    Background:

    • Surface electromyogram (sEMG) is crucial for neurorehabilitation and human-machine interfaces (HMI).
    • Individual variations in sEMG present challenges for multi-user HMI but suggest potential for biometrics.
    • High-density sEMG (HD-sEMG) captures detailed spatial muscle activation patterns beyond temporal features.

    Purpose of the Study:

    • To introduce and evaluate high-density surface electromyogram (HD-sEMG) as a novel method for personal identification.
    • To leverage the unique spatial patterns of muscle activation for biometric authentication.

    Main Methods:

    • Acquired 64-channel HD-sEMG signals from 22 subjects during isometric finger muscle contractions.
    • Focused on analyzing high-resolution spatial patterns of muscle activation.
    • Utilized subject-specific HD-sEMG data for personal identification.

    Main Results:

    • Achieved a 99.5% accuracy rate in identifying individual subjects.
    • Demonstrated the effectiveness of HD-sEMG in distinguishing individuals based on unique muscle activation patterns.
    • Confirmed the significant individual differences in HD-sEMG characteristics.

    Conclusions:

    • HD-sEMG shows exceptional potential as a biometric modality for personal identification.
    • Subject-specific HD-sEMG patterns may stem from unique neural and biomechanical factors.
    • Findings could inform the design of personalized rehabilitation robots and enhance understanding of human movement.
