Abstract
The electrode array is a device for making electrical contacts with cellular tissue or organs. The electrode array includes an assembly of electrically conductive electrodes arising from a substrate where the electrodes are hermetically bonded to the substrate. The electrodes also include an insulating layer which leaves at least one zone or at least one hole exposed for making focused electrical contact with the tissue. A hole passing completely or partially through the electrode may further provide an anchor to the living tissue, thereby stabilizing the array with respect to the tissue being examined. Also, a method of manufacture of an electrode array and associated circuitry is disclosed.
