What is an electrostatic discharge?

Electrostatic discharge (ESD) is the release of static electricity when two objects come into contact. Familiar examples of ESD include the shock we receive when we walk across a carpet and touch a metal doorknob and the static electricity we feel from clothes coming out of the dryer. Lightning is also electrostatic discharge.

While most of ESD events are harmless to the human body, they can cause challenging and expensive problems in certain industrial environments. Static electricity is a problem for electronic and medical device manufacturing, vehicle fabrication, industries that use plastics and paper, and ones that need clean room environments. ESD issues can slow production, negatively affect product quality issues, attract contaminants and create safety issues.

The principle of electrostatic discharge：

1.Electrostatic discharge: It is the transfer of electric charges between two objects with different electrostatic potentials (voltages). That is, an electric current is generated during the movement of the electric charge.

Human body discharge: It is a partial discharge that occurs near the tip of a charged body or a place with a very small radius of curvature. Corona discharge may be accompanied by a slight hissing sound and a faint pale purple light. Corona discharge generally poses no risk of ignition (human body discharge).

 Therefore, when working in industrial environments such as the electronics industry, the automotive manufacturing industry, and the aerospace manufacturing industry, workers need to wear ESD Clothing to avoid damage, failure, or shortened lifespan of electronic components caused by their own static electricity.
