What is polygraph?

A polygraph, colloquially referred to as a lie detector, is a sophisticated instrument employed to quantify and document physiological parameters, including heart rate, blood pressure, respiration, and skin conductivity. Its application involves administering a series of questions to an individual, with the objective of discerning potential physiological responses indicative of deception.
