| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 107 === Electromyogram (EMG) signals have attracted much attention and have been applied widely. EMG signals have been used to evaluate the functional status of skeletal muscles and assist in neuromuscular training and rehabilitation. The commercial EMG acquisition systems are costly, so many researchers have provided low-cost solutions. Although the wireless acquisition systems are realized, the transmission speed is not sufficient for high-sampling and multi-channel measurement. The purpose of this work is to implement a low-cost and wireless multi-channel surface EMG acquisition system. Using wearable EMG sensors combined with a microcontroller unit and a Wi-Fi module, the measured surface EMG signal samples can be forwarded to the host immediately for further processing and additional applications. Besides, the proposed system was validated by applying the commercial wireless EMG detection systems. The results show that most of the correlation coefficients are over 0.9 that represent moderate to high relative agreement between the commercial and the proposed system.
