BSL PRO Signal Processing Labs are a series of lessons that explain how to create and test the types of electronic circuits used in Biomedical Engineering (BME). The Signal Processing Labs use the BIOPAC SS39L Signal Processing Breadboard with Interface Cables and Electrode Interface.
Students learn that the human body can be studied by viewing the potential difference (Voltage) between strategically placed surface electrodes, and use electronic circuits to view and record the potential difference between surface electrodes. Electrode leads connect the electrodes to the circuit. Most signals from physiological activity have small amplitudes and must be amplified and processed before they can be viewed in a meaningful way.
Concepts introduced include the basics of amplifiers (with special emphasis on the biopotentials), Gain, Common-mode rejection (CMR), Electrode polarization, Frequency response, Input impedance, Signal noise and drift, Filters, and ECG circuit requirements.

View AllThe Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies in monitoring respiration and cardiovascular activity. The coupling between peripheral microcirculation and slow breathing: The purpose of this study was to investigate the coupling of breathing movements and microcirculatory blood […]
