A lie detector is a machine that monitors brain waves and heart rate to be able to tell if a person is telling the truth.
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.

yes people can it actually detects how nervous u are not really a lie detector
A lie detector test follows you pulse, if you are asked a question and your heart rate rises or falls then it will be a lie. If you can regulate your pulse you cannot be detected on a lie detector
It is a machine that detects changing in blood pressure, heart rate and other body rhythems to detect false statements.
The lie detector, or polygraph, was developed in California. The first successful polygraph machine was created by John A. Larson in the early 1920s while he was working at the Berkeley Police Department. Later, the device was further refined by Leonarde Keeler, also in California.

No it would not. If you believe it's the truth, the machine won't know otherwise. It measures the changes in your body when you consciously lie (or otherwise become upset).
AHH a lie detector ANSWER by Engl1sh: A perfessional typically uses the term 'polygraph' test.
Yes, a sociopath can potentially pass a lie detector test even when lying. Lie detectors measure physiological responses such as heart rate and galvanic skin response, which can be influenced by anxiety and stress. Sociopaths may lack the emotional responses that typically trigger these physiological changes, allowing them to remain calm and potentially deceive the machine effectively. However, the accuracy of lie detector tests is still debated, and various factors can influence their reliability.
