Bio Pac System
The BioPac System
The BioPac system is a system that measures electrophysiological responses from people. At present, the system has three modules: one for galvanic skin response (GSR), one for heart beat frequency (ECG), and one for respiratory movement.These modules can be used individually or in combination with each other. Each module returns a signal that shows how the response that it measures changes over time. An example is shown in the figure below, which is a GSR measured across a period of about 30 seconds.
