History

A concise historical narrative of NAICS Code 334519-12 covering global milestones and recent developments within the United States.

  • The history of Lie Detection Equipment Manufacturing dates back to the early 20th century when the first polygraph machine was invented by John Larson in 1921. The machine was used to measure physiological responses such as blood pressure, pulse rate, and respiration rate to determine if a person was lying or not. The technology was further developed in the 1930s by Leonarde Keeler, who added a galvanometer to measure skin conductivity. In the 1960s, computerized polygraphs were introduced, which made the process more accurate and efficient. In recent years, advancements in technology have led to the development of more sophisticated lie detection equipment, such as eye-tracking devices and brain scanners. In the United States, the use of lie detection equipment has been controversial, with some states banning the use of polygraphs in criminal investigations. However, the technology is still widely used in the private sector, such as in pre-employment screenings and investigations. In recent years, there has been a growing demand for more accurate and reliable lie detection equipment, which has led to the development of new technologies such as fMRI-based lie detection. Overall, the industry has seen steady growth in recent years, driven by the increasing demand for lie detection equipment in both the public and private sectors.
