The Design and Analysis of a Static and Extremely Low-Frequency Magnetic Field Stimulation Platform for Cell Prolifation Inhibition

It is known that tumor cells can be influenced by extremely low-frequency magnetic field stimulation. However, the optimal field strength and frequency have not yet been fully determined. In this paper, a static and extremely low-frequency magnetic field stimulation system with adjustable frequency and magnetic flux density was proposed. Additionally, a new planar stimulation coil with a printed circuit board is proposed which cooperates with the system. The field distribution of the stimulation system was simulated by numerical computation and the principle of the system was also analyzed. It was shown that the proposed stimulation system with coils could induce a wide range of extremely low-frequency magnetic fields and could accelerate the optimization process of field parameters.
