There is a physical field of charge-charge interaction in the space around any charged object, which is called electric field. When the charge carried by an electrostatically charged body is stationary and does not move directionally, an electrostatic field (called static electricity) is formed in the surrounding space. According to the relationship between electrostatic field and biological ions, high-voltage electrostatic field is used to adjust the acid-base balance of human blood, improve the autonomic nervous system and improve human immune function, so as to achieve the purpose of preventing and treating diseases, which is called electrostatic therapy or Franklin electrotherapy.

Electrostatic mechanism of energy health-preserving instrument: through cutting-edge high-tech treatment, high-voltage static electricity is given to human body in insulation state, so that high-voltage electrostatic field is formed around human body. Make the human body generate electrostatic induction and polarization, supplement the negative energy of the human body, and enhance the permeability of cells.
