MYOELECTRICITY MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a myoelectricity measuring instrument capable of calculating both of an muscle force exhibited and a muscle fatigue extent, and miniaturizing the instrument.

SOLUTION: A measuring/calculation part 1 is provided with an electrode part 10 detecting a potential difference between two points of the muscle; an amplification part 11 amplifying the potential difference detected by the electrode part; a signal processing part 12 comprising Fourier calculating means 12b performing an FFT (Fast Fourier Transform) to a potential difference signal amplified at the amplification part 11 to provided a frequency power spectrum distribution, real-time muscle force exhibited calculating means 12c integrating the frequency power spectrum distribution to find the exhibited muscle force based on the integral computation value, and real-time muscle fatigue calculating means 12d performing a frequency analysis to the frequency power spectrum distribution to find the muscle fatigue extent; and a data transmission part 13 wirelessly transmitting data of the exhibited muscle and the muscle fatigue extend found by the signal processing part 12 to a display part 2.
