This five system BioHarness solution is ideal for small group studies. BioHarness with AcqKnowledgeTM software is a state-of-the-art lightweight portable biological data logger and telemetry system. The subject wears the BioHarness around the chest to record a wide range of physiological signals. The system allows the subject to wear the system away from the lab when used in the data logging mode. The logged data is downloaded to the AcqKnowledgeTM software through the BioHarness cradle that is included with the system. The BioHarness monitors, analyzes and records a variety of physiological parameters - ECG, respiration, temperature, posture, and acceleration. The system also operates in RF (Radio Frequency) transmitting mode for live viewing of data. This mode is convenient when the subject is in the lab or in range to the receiver. Applications include physiology, psychology, psychophysiology, exercise physiology, ergonomics, human factors, and more.
