A "lie detector" test--more correctly called a polygraph test-- is really a whole battery of tests. It measures physical changes in our bodies when we undergo psychological stress. Measurements include pulse (how fast your heart beats), blood pressure, respiration (how fast you breath) and how much your hands perspire. I think they say something about "galvanic skin resistance", but it comes down to sweat. The more you sweat, the better your skin conducts electricity. That is what this project does: it measures how good you, or anything, conducts electricity. Principle : It is based on the principle of Galvanic Skin response under various conditions depending on sweat or relaxing of body.
