Abstract
Abstract A very small electrode array is disclosed, having numerous, small, sharp, conductive protuberances (needles) which penetrate nerves, organs, muscle or other body part for sensing the electrical activity therein or to provide electrical stimulation. The protuberances are carried on a base and there is included electrical conductors connecting the protuberances to terminals, such as bonding pads, for connection to other electrical circuits. Thus, a method of connecting to living tissue is disclosed. Also, a method of manufacture of an electrode array and associated circuitry is disclosed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
A method for making an electrode array comprising the following steps: step (a): obtaining a base with a non-conductive surface, then step (b): depositing a layer of electrically conductive material atop the non-conductive surface, and step (c): defining sites upon the layer of electrically conductive material for an array of protuberances, and then step (d): depositing electrically conductive protuberances upon the sites for the array, the protuberances having tips, and step (e): forming conductors for electrically connecting to the protuberances by partially removing the layer of electrically conductive material, and then step (f): depositing a dielectric coat upon the protuberances, exclusive of the tips.
Claim 2
