    Researchers developed a novel electric prosthesis using muscle vibration, detected via a piezoelectric wire sensor, for accurate finger movement control. This innovative approach overcomes ambient noise interference, enhancing prosthetic functionality.

    Area of Science:

    • Biomedical Engineering
    • Rehabilitation Technology
    • Sensor Technology

    Background:

    • Developing advanced electric prostheses for natural finger movement remains a significant challenge.
    • Existing myoelectric prostheses face limitations, prompting research into alternative biological signals.
    • Muscle sound, unaffected by skin impedance, offers a promising signal for prosthetic control.

    Purpose of the Study:

    • To investigate the efficacy of muscle sound and bulge, termed Muscle Vibration, for motion estimation in electric prostheses.
    • To evaluate the accuracy of a piezoelectric wire sensor in detecting Muscle Vibration for prosthetic control.
    • To determine the impact of ambient noise on the motion estimation accuracy of the developed system.

    Main Methods:

    • Muscle sound and bulge were measured as micro-vibrations using a 0.5 mm diameter piezoelectric wire sensor.

  • Motion estimation algorithms were developed and tested under varying ambient noise conditions.
  • The discrimination rate of movements was assessed at noise levels up to 80 dB.

    • Main Results:

    • The piezoelectric wire sensor effectively estimated motion using Muscle Vibration.
    • An average discrimination rate of 85.7% was achieved even at an 80 dB ambient noise level.
    • Discriminators demonstrated over 90% accuracy for movement detection across different noise conditions, indicating robustness.

    Conclusions:

    • Muscle Vibration measured with a piezoelectric wire sensor provides a robust method for motion estimation in electric prostheses.
    • The system's performance is not significantly affected by environmental sound changes.
    • This technology offers a promising pathway for developing more responsive and reliable electric prostheses.
