Development of a Portable and Wireless Surface EMG


Article Preview

The objective of this study was to develop a portable, wireless surface EMG of a noninvasive type. The limitations of the existing system include its large size and the necessity of a wire. Therefore, this study focused on the development of a portable and wireless type of EMG. The developed EMG, which has 10 channels, is composed of an electrode for the measurement of the EMG signal, a preamplifier for initial processing, a second amplifier, an A/D converter, and a Bluetooth module for wireless communication. The communication of the developed EMG used a UART (Universal Asynchronous serial Receiver and Transmitter) and Bluetooth protocols. The rate of serial communication was set to 723kbps. This system is able to obtain 2,000 Hz in each channel. The data transfer success rate of the developed EMG is 100%.
