The Physiological Sounds Microphone (SS17L) connects to the MP3X hardware unit. The SS17L can be used with the SS19L Noninvasive Blood Pressure Cuff or as a stand-alone device.
If you use it with the Blood Pressure Cuff, you can record the Korotkoff sounds for easy determination of systolic and diastolic blood pressure (see Application Note 130 – Blood Pressure Measurement). When used on its own, it can record a variety of acoustical signals, including heart sounds and sounds associated with rubbing or grinding (e.g. Bruxism).
The acoustical transducer element is a Piezo-electric ceramic disk which is bonded to the interior of a metallic circular housing.

The 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 […]
