Abstract: Miniature multifunctional antennas and related techniques are disclosed that are capable of wide bandwidth operation. In some embodiments, the antennas are capable of being reconfigured in the field for optimal performance in different frequency band configurations (e.g., a single wide instantaneous bandwidth, multiple smaller bands, etc.) and/or for purposes of self healing. In some embodiments, the antennas can be reconfigured in the field to achieve different polarizations (e.g., vertical, horizontal, circular). The antennas can be implemented in a very compact manner making them ideal for use in devices and platforms where size and weight are a concern.

Abstract: A glucose fuel cell for reception into a given constrained volume of implantation in a vertebrate in which the glucose fuel cell has access to fluid containing glucose. The fuel cell includes an anode adapted to oxidize the glucose, a cathode adapted to reduce an oxidant, and a membrane disposed between the anode and the cathode and separating the anode from the cathode. At least one of the anode or cathode define a flexible sheet that is geometrically deformed to be receivable into the given constrained volume of implantation and increase volumetric power density. Related methods of making a glucose fuel cell of this type and implantable assemblies including the glucose fuel cell are also disclosed.
