ABSTRACT:
Apparatus and methods for measuring the properties of a material by employing a driven electrode, a sensing electrode and a shunting electrode. The shunting electrode is disposed in proximity to the driven and sensing electrodes and functions to increase the sensitivity of electrical measurements made between the driven and sensing electrodes by influencing the coupling of the imposed electric field to the sensing electrode to a degree related to the properties of the material under test.
