lie detector
A lie detector picks up changes in your pulse and heart rate. Generally when you tell a lie, your pulse will increase because you don't want to tell the person what you are hiding and consequently become nervous. It has been confirmed that a lie detector can not be trusted fully to determine whether you are lying or not.
