Abstract

Designs, strategies and methods to form energization elements comprising polymer electrolytes are described. In some examples, the biocompatible energization elements may be used in a biomedical device. In some further examples, the biocompatible energization elements may be used in a contact lens.

First claim

What is claimed is:

1. A biomedical device comprising:
an electroactive component;
a primary battery including an anode current collector, a cathode current collector, an anode, a dry polymer electrolyte comprising an ionic species, and a transition metal oxide cathode, wherein the dry polymer electrolyte is laminated to a transition metal oxide deposit and to the anode; and
a first biocompatible encapsulating layer, wherein the first biocompatible encapsulating layer encapsulates at least the dry polymer electrolyte, the metal oxide deposit, and the cathode current collector.

2. The biomedical device of claim 1 , wherein the anode comprises zinc,
wherein the anode and the anode current collector are a single layer, and
wherein the transition metal oxide cathode comprises manganese.

3. The biomedical device of claim 2 , wherein the composition of the electrolyte comprises poly (vinylidene fluoride).

4. The biomedical device of claim 3 , wherein the composition of the electrolyte comprises zinc ion.

5. The biomedical device of claim 4 , wherein the composition of the manganese dioxide cathode comprises jet milled electrolytic manganese dioxide.

6. The biomedical device of claim 4 , wherein the composition of the manganese dioxide cathode comprises poly(vinylidine fluoride).

7. The biomedical device of claim 6 , wherein the composition of the manganese dioxide cathode comprises carbon black.

8. The biomedical device of claim 7 , wherein the zinc anode is a foil of zinc.

9. The biomedical device of claim 1 , wherein the battery comprises a seal in encapsulating films that enclose the battery portions not used for making external contacts.

10. The biomedical device of claim 1 , wherein the thickness of the battery is less than 1 mm at least along a first dimension of the extents of the battery.

11. The biomedical device of claim 1 , wherein the thickness of the battery is less than 500 microns at least along a first dimension of the extents of the battery.

12. The biomedical device of claim 1 , wherein the thickness of the battery is less than 250 microns at least along a first dimension of the extents of the battery.

13. The biomedical device of claim 12 , wherein the shape of the battery is curvilinear.
