Electromyography (EMG) is a set of techniques used to acquire signals from muscles (myoelectric). Among the many branches in this field of study, is the use of surface electrodes for signal acquisition from the skin surface of an individual. This work presents the development of an electronic device to capture eight signals from muscle group of a human arm. It was studied different processing techniques, types of simulations and acquisition ways about surface electromyography (sEMG). A printed circuit board was designed to accommodate all the electronic components, including the microcontroller C2000, the Bluetooth module JY-MCU, the ADS1299 front-end and the supply system. The flow of data starts on the electrodes connected to the skin of the arm of the individual and, with the help of cables, a connection is created to the ADS1299 analog-digital converter. Then, the data in digital form are sent to the microcontroller, starting the wireless transmission (Bluetooth) with a computer. An application was created using the software LabVIEW™ in order to receive, display and record the incoming electromyography signals from all channels. As a way to evaluate data, the product ADS1299EEG Perfomance Demonstration Kit was used. Lastly, comparing the results of the developed system with the evaluation module, it can be said that the goal of this work was achieved. The results were satisfactory, which offer multiple possibilities of further development. |
