2. For years, police departments, the FBI, and the CIA have used polygraphs(lie detectors)to check the truth of what someone is saying. These machines record changes in a person`s blood pressure breathing, and the skin`s electrical conductivity; these are responses that indicate that a person is lying. Recent technological advances, however, have taken this concept one step further. Telephones and even digital watches may soon be turned into small versions of lie detectors. Such miniature Psychological Stress Evaluators (PSEs) would, unlike current polygraphs, detect lying by picking up `microtremors` in a person`s voice. Microtremors, which are movements of the voice too slight to be noticed by the human ear, vary accerding to the degree of stress. Imagine having a PSE on your home phone or on your wristwatch! You would usually know if someone was avoiding the truth!
