    Abstract: A plastic, waveguide-fed, horn antenna is manufactured using a three-dimensional (3D), polymeric micro hot embossing process. Two cavity resonators may be designed to reduce the impedance mismatch between the pyramidal horn antenna and the feeding waveguide. The waveguide-fed antenna may be fabricated using a self-aligned 3D plastic hot embossing process followed by a selective electroplating and sealing process to coat an approximately 8 μm-thick gold layer around the internal surfaces of the system. As such, this plastic, low-cost manufacturing process may be used to replace the expensive metallic components for millimeter-wave systems and provides a scalable and integrated process for manufacturing an array of antenna.

    Abstract: A method of fabricating a microstructure is disclosed. The method includes providing a substrate for forming an interface region and an elongated portion extending away from the interface region. A patterned, non-planar etchable structure is formed on one side of the elongated portion of the substrate. An unetchable membrane layer is deposited atop the etchable structure. At least one etching hole is formed in the membrane layer. The etchable structure is etched by placing an etchant into the etching hole to form a cavity underneath the membrane layer, thereby producing a shaft.

    Abstract: A miniaturized microbial fuel cell is described deriving electrical power from the biological activity of microbes, typically the metabolism of glucose by baker's yeast. Microfabrication techniques are used to miniaturize the components as well as the overall fuel cell and are capable of integration with other biomedical and implantable devices. Substantial reductions in both the size and the cost of implantable systems are thereby achievable. Electrode structures are used that facilitate electron transfer and power production giving favorable power densities in a miniature fuel cell. In addition, the microbial fuel cell of the present invention extracts glucose or other metabolite(s) from the ambient body fluids as its fuel, thus achieving a renewable, long-term power source for implantable biomedical devices.
