NOVELTY - A method of forming three-dimensional biocompatible energization elements (300), involves receiving a substrate having a three-dimensional surface (310); forming at least two conductive traces (330, 340) on the surface; depositing an anode chemical formulation on at least part of one of the traces to form an anode (350); depositing a cathode chemical formulation on at least part of another of the traces to form a cathode (360); depositing an electrolyte over anode and the cathode; and encapsulating anode, cathode, and electrolyte using a biocompatible material.    USE - For forming three-dimensional biocompatible energization elements (claimed) for implantation within or upon biocompatible devices such as medical device e.g. implantable pacemakers, electronic pills for monitoring and/or testing biological function, surgical devise with active components, contact lenses, infusion pumps, neurostimulators, defibrillators, stents, neural interfaces, and medicament dispersal devices.    ADVANTAGE - The method forms three-dimensional biocompatible energization elements that are implantable to devices having a very small size.    DETAILED DESCRIPTION - A method of forming three-dimensional biocompatible energization elements (300), involves receiving a substrate made from an insulating material, and having a three-dimensional surface (310); forming at least two conductive traces (330, 340) on the surface; depositing an anode chemical formulation on at least part of one of the conductive traces to form an anode (350); depositing a cathode chemical formulation on at least part of another of the conductive traces to form a cathode (360); depositing an electrolyte over anode and the cathode; and encapsulating the anode, the cathode, and the electrolyte using a biocompatible material. The method further involves roughening and/or coating a portion of the surface; depositing a bridge chemical formulation in contact with the anode and the cathode; and removing the substrate to separate the three-dimensional biocompatible energization element. The electrolyte is a gel. The conductive traces include metal particles. An INDEPENDENT CLAIM is included for a three-dimensional biocompatible energization element, comprising substrate made from an insulating material, and having a three-dimensional surface; at least two conductive traces on the surface; an anode made of an anode chemical formulation on at least part of one of the conductive traces; a cathode made of a cathode chemical formulation on at least part of another of the conductive traces; an electrolyte over anode and the cathode; and a biocompatible encapsulant over the anode, the cathode, and the electrolyte.
