Static Electricity in the Human Body
The human body is a unique electrostatic system. Under normal conditions, the human body itself is a conductor of static electricity, while clothing, shoes, and socks, which are in close contact with the body, are often made of insulating materials. This means that a capacitor is formed between the human body and the ground, capable of storing static energy. During daily activities, the human body system can acquire a certain amount of charge for various reasons. Whether in microelectronic devices or flammable and explosive environments, the human body is a dangerous source of static electricity. When a charged human body system approaches a grounded conductor, electrostatic discharge may occur. If the energy of the electrostatic discharge exceeds the sensitive energy of the hazardous area, an electrostatic accident will occur.
Therefore, in the field of electrostatic protection, how to suppress or eliminate static electricity in the human body is of great significance.
The phenomenon of static electricity in the human body is familiar to people in daily life. For example, when the indoor air is dry, when we walk on a carpet and then open a door or touch a heating pipe, we often hear a "snap" and feel an electric shock in our fingertips. When taking off synthetic fiber clothing in the dark, we not only hear a "snap" but also see flashing sparks. These phenomena are all examples of electrostatic discharge in the human body.
