Abstract:
1. A bio probe having a base and a tip, and comprising: (a) a longitudinal core of substantially rigid material, wherein the longitudinal core is substantially circular in cross-section from the base to the tip of the core and the longitudinal core tapers from the base to the tip; (b) a first layer of dielectric material, supported by and substantially circumferentially surrounding said core; (c) a set of conductors, each conductor extending longitudinally along said first layer of dielectric material, the set of conductors substantially circumscribing the core, wherein said set of conductors are made from conductive material that is deposited directly upon said first layer of dielectric material and each adjacent pair of conductors of said set of conductors is mutually separated by a trench running longitudinally along the length of said bio-probe; (d) a second layer of dielectric material, substantially covering each of said set of conductors; and (e) for each said conductor, an aperture defined through said second layer of dielectric material to said conductor, thereby defining an electrode.
