Degradable implantable battery |
| 摘要 |
A biodegradable battery is provided. The battery includes an anode comprising a material including an inner surface and an outer surface, wherein electrochemical oxidation of the anode material results in the formation of a reaction product that is substantially non-toxic and a cathode comprising a material including an inner surface and an outer surface, the inner surface of the cathode being in direct physical contact with the inner surface of the anode, wherein electrochemical reduction of the cathode material results in the formation of a reaction product that is substantially non-toxic, and wherein the cathode material presents a larger standard reduction potential than the anode material. |

1. A biodegradable battery comprising:
an anode comprising a material including an inner surface and an outer surface, wherein electrochemical oxidation of the anode material results in the formation of a reaction product that is substantially non-toxic; a cathode comprising a material including an inner surface and an outer surface, the inner surfaces of the cathode being separate from the inner surface of the anode, and a biodegradable coating disposed over the outer surface of the cathode and a first portion of the outer surface of the anode, such that a second portion of the outer surface of the anode is uncoated by the biodegradable coating, wherein electrochemical reduction of the cathode material results in the formation of a reaction product that is substantially non-toxic, and wherein the cathode material presents a larger standard reduction potential than the anode material. |
