| Research Abstract |
In this study, the displacement MMG (mechanomyogram) array transducer within 50x50 mm, composed of 25 photo-reflectors which could measure micro-distance, was developed. The multichannel measurement with 10 kHz sampling and analysis of displacement MMG were proposed. Using this array transducer, the spatial propagation map of displacement MMG of biceps brachii was drawn and the propagation velocity considering the direction of muscle fiber was calculated. The propagation aspect of muscular fiber contraction was reported during an isometric voluntary contraction and twitch contraction by electro-stimulation.
