capacitive measurement system was developed. The capacitive measuring was done by active electrodes as an impedance converter, which enables a low-impedance processing of the measured potential φ G . Figure 2 shows the measurement of a potential φ G with a capacitive electrode. The lower part of the Figure shows the corresponding equivalent circuit. Fig. 2 Measuring arrangement for impedance measurement with two or four electrodes and the corresponding equivalent electric circuit. The capacitor C k represents the capacitive coupling between the electrode and the

Introduction Electrical properties of biological tissues have been studied for over a century [ 1 ]. A large variety of different biological tissues have been investigated with the help of impedance spectroscopy, a detailed review on various human and animal tissue and blood samples can be found, e.g., in the review by Gabriel et al. [ 2 ]. Fricke and Curtis [ 3 ] investigated the impedance of yeast cell suspensions in the early 1930´s. They concluded that the impedance at the surface of the yeast cell is derived from a poorly conducting membrane which acts as a

in 32% of the cases [ 41 ]. Clinical background for REG Cerebral Blood Flow The brain has ongoing, substantial energy requirements but minimal stores of energy-generating substrates. As a result, it is completely dependent on a continuous, uninterrupted supply of substrate (oxygen, glucose). Although the demand by the brain for energy-generating substrates is substantial (the central nervous system consumes 20% of the oxygen (that is, 170 mmol/l00 g per min or 3-5 ml O 2 /100 g brain tissue per mm or, approximately, 40-70 ml O 2 /min) and 25% of the glucose (31

was then made out of Silicon Mold substrate fabricated with the steps mentioned as follows: Seed metallization of Nickle Vanadium (NiV) alloy was carried out at the specifications of 1000 seconds of time, 5 mtorr of pressure, and power of 157 W using a sputter system. Electroplating of Nickle was proceeded for up to 6 hours and 13 mins of deposition procedure to get the required thickness for the Ni shim. The silicon wafer was removed afterwards using wet etching KOH process in fume-hood with 25 wt % of KOH at 80 °C for 6-8 hours. Figure 5 shows the Nickle shim
