　　Police around the world have for almost 100 years relied on lie detectors to help spot criminals. But there has long been much skepticism in the scientific and legal communities about the lie detector's reliability. Hopefully, it could soon be no longer in use.

　　Researchers in Britain and the Netherlands have made a breakthrough, developing a more reliable method to help conduct interviews. Rather than just record changes in pulse, blood pressure, sweating and breathing, the new system involves monitoring full-body motions to provide an indicator of signs of guilty feelings. There is a basic fact that liars tend to keep moving their hands and feet and so an all-body motion suit will pick this up. The suit contains 17 sensors that record movement in 23 joints up to 120 times per second.

　　"The lie detector has been around since the 1920s and by measuring physiological stress caused by anxiety, you can only get a success rate of about 60%.", said Ross Anderson, professor of security engineering at Cambridge University.

　　He said the new method, by contrast, achieved a reliability rating of over 70% and he was quite sure that they would be able to do better. In one of their experiments, the team has already achieved more than 80%.

The experiment involved 180 students and employees at Lancaster University, of which half were told to tell the truth and half to lie. They were each paid ￡7.50 for their participation in the 70-minute experiment, involving two test.
