 Polygraph - Wikipedia, the free encyclopedia
A polygraph (commonly yet incorrectly referred to as a lie detector) is a device that measures and records several physiological variables such as blood pressure, heart rate, respiration and skin conductivity while the subject is asked a series of questions.
