Diseño y construcción de un módulo didáctico para la adquisición y análisis de señales ECG, EEG y EMG

Abstract

This project consist about the development of a module to acquisition of ECG, EEG and EMG signals and visualization of this, in order to have information for development practices in a Biomedical Laboratory and contribute to the teaching and study of Engineering students around biosignal processing. The ECG and EMG signals was acquired with surface electrodes and EEG signals with an EmotivEpoc device consisting of 14 surface electrodes. The Epoc device used an interface with Labview and Openvibe software with dll libraries. The development was based on LabView software to recognize the parameters of ECG and EMG signals with Butterworth and Notch digital filters. We use Matlab software for visualization of biosignalsand to develop some processing techniques such as Tom Hopkins algorithm to detect the QRS complex of the ECG signals acquired with the module. For the EEG signal analysis software was used Emotiv and free software Openvibe.
