PRINTED BIOFUEL CELLS

摘要

Methods, systems, and devices are disclosed for implementing a biofuel cell device for extracting energy from a biofuel. In one aspect, a biofuel cell device includes a substrate, an anode including a catalyst to facilitate the conversion of a fuel in a biological fluid in an oxidative process that releases electrons captured at the anode, thereby extracting energy from the fuel substance, a cathode configured on the substrate adjacent to the anode and separated from the anode by a spacing region, and a load electrically coupled to the anode and cathode via electrical interconnects to obtain the extracted energy as electrical energy.

主权项

1. A biofuel cell device, comprising:
a substrate; an anode formed on the substrate of an electrically conductive material, the anode including a catalyst to facilitate the conversion of a fuel substance in a biological fluid to a first product in an oxidative process that releases electrons captured at the anode, thereby extracting energy from the fuel substance; a cathode configured on the substrate adjacent to the anode and separated from the anode by a spacing region, the cathode formed of a material that is electrically conductive and capable of reducing an oxygenated substance in the biological fluid to a second product in a chemical reduction process in which the second product gains electrons; and a load configured of one or more electrical circuit elements electrically coupled between the anode and the cathode via electrical interconnects to obtain the extracted energy as electrical energy.
