Implementation results of biosignals acquisition lessons for Biomedical Engineering Lab

Abstract

Previous works in analysis and design of biosignals acquisition have been done in Universidad Politécnica Salesiana, In this context, this paper presents the results of implementation process of biosignals acquisition lessons with Biopac MP45 by undergraduate students. For each biosignals a protocol acquisition are proposed to safety. Different implementation lessons about in Electromyography (EMG), Electrocardiography (ECG), Electroencephalography (EEG) and Electroculography (EOG) are analyzed, including both frequency and temporal domain. To EMG acquisition lessons a characteristics analysis of amplitude and frequency changes by the wrist flexor when, fist is done. In this context, in ECG acquisition, the Einthoven triangle and derivative and temporal intervals analysis are made. The same form, to EEG acquisition an analysis of how change the frequency activity of cortex when induced to alpha state. Finally to EOG acquisition a verified of behavior signals in ocular movements are made. All this process are implemented by undergraduate students under supervision. The results show a good performance and a correct biosignals acquisition method.
