Abstract

High-sensitivity human muscle-vibration measurement (MMG) sensor adapted to clinical use is presented. The muscle vibration phenomenon is modeled and investigated to optimize the measurement technique. The sensor uses an acoustic impedance adaptation technique to convert the skin surface vibration in terms of acoustic pressure, which is sensed by a microphone. The device is calibrated and gives the real amplitude of the vibration. It is also well fitted to measure other physiological vibrations in the 2 Hz-1 KHz range.

摘要

介绍了一种适用于临床的高灵敏度人体肌肉振动测量（MMG）传感器。对肌肉振动现象进行建模和研究，以优化测量技术。该传感器采用声阻抗适配技术，将皮肤表面振动转换为声压，由麦克风进行传感。该设备经过校准，可给出振动的实际幅度。它也非常适合测量2Hz至1kHz范围内的其他生理振动。
