Abstract
Methods and apparatus to form three-dimensional biocompatible energization elements are described. In some embodiments, the methods and apparatus to form the three-dimensional biocompatible energization elements involve forming conductive traces on the three-dimensional surfaces and depositing active elements of the energization elements on the conductive traces. The active elements are sealed with a biocompatible material. In some embodiments, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.

A method of forming three-dimensional biocompatible energization elements, the method comprising:
- receiving a substrate made from an insulating material, the substrate having a three-dimensional surface;
- forming two or more conductive traces on the three-dimensional surface;
- depositing an anode chemical formulation on at least part of one of the conductive traces to form an anode;
- depositing a cathode chemical formulation on at least part of another of the conductive traces to form a cathode;
- depositing an electrolyte over at least part of the anode and the cathode;
- and
- encapsulating the anode, the cathode, and the electrolyte using a biocompatible material to form a three-dimensional biocompatible energization element.
