Abstract :
Measurements of the impedance of cell-covered electrodes can be used to detect the presence of cells, their motion, and can yield information about biological processes. In this paper we present the results of finite element modeling of the impedance of cell-covered electrodes. The emphasis is on the behavior of small electrodes comparable to the cell size.
