| Research Abstract |
The purpose of this study is to develop the computer interface which uses neuromuscular information from capacitively-coupled multi-channel surface EMG signals and then which can record over clothes.
In this study, firstly, how shapes of capacitively-coupled electrode effect output signal is examined with the hardware model. The result shows that signal-to-noise ratio can be reduced with guarding around the electrode plates. Also, the relationship between signal-to-noise ratio and muscle conduction velocity is examined with simulated EMG model. Based on the simulated EMG model, he relationship between signal-to-noise ratio and kurtosis is clarified. From the result, we can easily measure signal-to-noise ratio of real EMG signal with kurtosis.
This study made advantages for developing the computer interface with capacitively-coupled multi-channel surface EMG signals.
