[0002] The anti-static wrist strap is a tool for eliminating static electricity on human skin that is currently widely used by various factories, research institutes, pharmaceutical companies and chip manufacturers. It has a simple structure and is easy to wear. It provides a good way to eliminate static electricity on human skin. Proper use can effectively reduce the damage of human static electricity to static-sensitive products, and is an important means to ensure product quality. At present, there are a large number of anti-static wrist strap testers and automatic monitoring systems on the market, and the quality varies. Some cannot quantitatively measure the resistance of the inner and outer surfaces of the anti-static wrist strap, and some measurement methods have fluctuations of 3 to 5 orders of magnitude. Some are greatly affected by elastic deformation, pressure and environmental factors, making the results less accurate and unable to effectively evaluate the quality of the inner and outer surfaces of the anti-static wrist strap.
