Abstract :
The authors have investigated a nondestructive measurement method of various permittivity in a human brain. To establish the method, they have used a measurement method of a long distance small parallel-electrode air capacitor with additional electrodes, in which an electric potential equals to one of the respective main measurement electrodes. Such an air capacitor will be utilized to measure the permittivity which depends on the temperature in a brain. In this paper, the electric lines of force of a simulated human brain have been visualized using Finite Element Method (FEM) and the predicted capacitance based on the method has been estimated
