New Lie Detector Detects Lies Through Nasal Temperatures

As we all know, the lie detector is generally used to ask the suspect's heart condition. After all, the polygraph measures the emotions of people, and now the lie detector has made new developments and began to measure the liars' nose temperature.

Polygraph detection is the identification of lies. The original “polygraph” is Polygraph. It is literally translated as a “multiple recorder” and is a device that records many physiological responses. It can be used in criminal investigations to assist in investigations to understand the psychology of the suspects being questioned. Status to determine whether it involves a criminal case. Accurately speaking, what the lie detector measures is actually not a lie, but an emotion. When lying, people's emotional fluctuations can lead to changes in the activities of the sponsored nervous system, and then change into physical changes, including faster breathing and swallowing. The increase in sweat and the rapid heartbeat are involuntary and difficult to control.

But at present, the way of measuring heartbeat on lie detectors is out of date, because many specially trained agents can not change their hearts when they lie.

According to the Spanish "Today" reported on the 12th, a research team at the University of Granada, Spain, has made new breakthroughs in the subject of lie detection. Researchers used precision instruments to measure the liar’s face and discovered that when lying, the nose temperature suddenly increased. After testing hundreds of liars, the scientists finally confirmed the results of the study.
