A lie detector, or polygraph, measures physiological responses such as heart rate, blood pressure, respiration, and skin conductivity while a person answers questions.

The polygraph is the best-known technique for psychophysiological detection of deception. The goal of all of these techniques is to detect deception by analyzing signals of changes in the body that cannot normally be detected by human observation.
