polygraph
noun
- a machine designed to detect and record changes in physiological characteristics, such as a person’s pulse and breathing rates, used especially as a lie detector
(Oxford English Dictionary)

John Larson, a University of California medical student, invented the modern polygraph machine in 1921. Also referred to as a lie detector, it has been used in police interrogation and investigation since 1924. The polygraph machine is still controversial among psychologists and is not always accepted in courts of law.
The theory is that when a person lies, the lying causes a certain amount of stress that produces changes in several involuntary physiological reactions. A series of different sensors are attached to the body, and as the polygraph measures changes in breathing, blood pressure, pulse and perspiration, it records the data on graph paper.
During a lie detector test, the operator asks a series of control questions that set the pattern of how an individual responds when giving true and false answers. Then the actual questions are asked, mixed in with filler questions. The examination lasts about 2 hours, after which the expert interprets the data.
The name polygraph comes from the fact that the machine records several different body responses simultaneously as the individual is questioned. It stems from the Greek polygraphos "writing much" (poly = much + graphos = writing).
