Abstract
Abstract A method of manufacturing a multiple microelectrode assembly is disclosed. Micromachining technology (such as micro-electrical-discharge machining technology, laser-beam micromachining, electron-beam micromachining) is used to manufacture an electrode/base assembly. The electrode/base assembly is placed within a container; a liquid material is placed into the container; the liquid material surrounds the electrodes of the electrode/base assembly and is allowed to solidify; and the solidified liquid material in combination with the electrode/base assembly is separated from the container. The bottom (or base) portion of the electrode/base assembly is then removed. The electrodes of the electrode/base assembly comprise a plurality of rod-like members of very small (on the order of 1 micron) metallic members of preselected dimension, shape and spacing, by which they are adapted in combination with the surrounding insulating material as a multiple microelectrode assembly.
