Abstract
An electrode and method of making same characterized by a biological material used as a substrate. The electrode is used primarily as a stimulation electrode, but could also be used to monitor electrical activity of neural tissues. The biological substrate is a chronically implantable material of treaterd human or animal tissue. The use of this material tends to prevent undue fibrosis and necrosis of the nerve tissue. An inner layer of a non-biologic dielectric may be used to increase to resistivity of the structure. Similarly an inner layer of shielding material may also be used.
