Abstract

A measurement device has a body defining an external periphery and comprises a two-dimensional array of electrodes disposed generally parallel to said external periphery of the body, an energisation source arranged to energise at least one of said electrodes, and a monitor arranged to measure an electrical parameter at least one of said electrodes. The energisation of an electrode by said energisation source causes an electric field to be established between at least one pair of electrodes, said electric field extending about said external periphery externally of said body.
