Analysis for development of biosignals acquisition manual for a biomedical engineering laboratory

Abstract

Biosignals acquisition is a fundamental task in biomedical engineering applications. A correct acquisition and a proper method for interpreting the data acquired are required in order to design control devices or monitoring systems. This paper presents the design of a manual for biosignals acquisition (EMG, EEG, EOG and ECG) using the Biopac MP 45 for theoretical and experimental lessons as a part of the activities of a biomedical engineering laboratory. In order to recognize patterns and variations in the biosignals, the lessons include mathematical analysis for EEG and EMG signals and temporal analysis for EOG and ECG signals. Also, a database to perform postprocessing work are acquired. The results obtained with the implementation of these lessons by undergraduate students were satisfactory.
