Abstract :
External noise sources such as movement artefact may interfere with mechanomyography (MMG) signal recording, compromising signal detection for electrically-powered prosthesis control. A novel coupled microphone-accelerometer sensor pair, intended to facilitate noise reduction, was designed and tested on a below-elbow amputee. Sample recordings demonstrate clear distinction between motion artefact and useful MMG signals.
