METHODS AND APPARATUS TO FORM BIOCOMPATIBLE ENERGIZATION PRIMARY ELEMENTS FOR BIOMEDICAL DEVICES

摘要

Methods and apparatus to form biocompatible energization elements are described. In some embodiments, the methods and apparatus to form the biocompatible energization elements involve forming cavities comprising active cathode chemistry. The active elements of the cathode and anode are sealed with a laminate stack of 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.

1. A biocompatible energization element comprising
a gap spacer layer; a first hole located in the gap spacer layer; a cathode spacer layer, wherein the cathode spacer layer is attached to the gap spacer layer; a second hole located in the cathode spacer layer, wherein the second hole is aligned to the first hole, and wherein the second hole is smaller than the first hole such that when the first hole and the second hole are aligned there is a ridge of cathode spacer layer exposed in the first hole; a separator layer, wherein the separator layer is placed within the first hole in the gap spacer layer and is adhered to the ridge of cathode spacer layer; a cavity between sides of the second hole and a first surface of the separator layer, wherein the cavity is filled with cathode chemicals; a first current collector coated with anode chemicals; a second current collector, wherein the second current collector is in electrical connection with the cathode chemicals; and an electrolyte comprising electrolyte chemicals, wherein the cathode chemicals, anode chemicals and electrolyte chemicals are formulated for a single discharging cycle of the energization element.
