Human Body Conductivity
★Exhibit Content: Human Body Conductivity ★Interaction: Electromechanical Interaction ★Operation: Hold the electrodes with both hands and observe the lighting effect. ★Exhibit Description: The exhibit consists of two electrodes, lights, a protective cover, etc. When visitors grip the two electrodes with both hands, the lights turn on. Utilizing the property that the human body is a conductor, the circuit is completed to generate current, and the motor drive circuit is activated to explain the concept of conductors. ★Scientific Principle: The human body contains a large amount of blood, lymph, and cerebrospinal fluid. These body fluids are mainly composed of water, in which various electrolytes are dissolved, such as calcium, sodium, potassium, and other trace elements. These trace elements often exist in the form of charged ions in body fluids and move directionally to form an electric current. Therefore, the human body has electrical conductivity and is prone to electric shock.
