Abstract
Bipolar and tetrapolar impedance measurements from a volume of biological tissue are compared. In the bipolar case, sensitivity is always positive and decreases with depth. However, for tetrapolar measurements the mean sensitivity is found to be zero over the surface plane, rising to a maximum at a depth proportional to electrode spacing
