Abstract
The dielectric properties of cells can be observed by injecting a low amplitude
current at different frequencies (1MHz~100MHz). The simulation research
is taken on the software platform named COMSOL Multiphysics. The electric
field and the cell model is created with prior information. By simulation,
it’s verified that at low frequencies, the region of interest (ROI) behaves
the conductivity characteristic while the electrical signal cannot pass
through the cell membrane due to its capacitor properties. With the excitation
frequency increasing, the ROI behaves more permittivity characteristic
that the current flowing through the cell membrane becomes more and the
current density increases. The research of the cell dielectric properties
provides an auxiliary method to diagnose the status of the cell.
