Method of manufacturing high volumetric density electrodes from self-aligning fiber powders

Title: Method of manufacturing high volumetric density electrodes from self-aligning fiber powders

Abstract

An electrode and a related method of manufacture are provided. The electrode includes a self-aligning active material having short fiber powders with a cylindrical morphology to increase the packing density from 0.74 to nearly 0.91. The short fiber powders self-align during a slurring coating process as a result of shear forces between a die and a foil. The resulting coating includes parallel short fibers in a closed packed arrangement, providing an increased volumetric capacity of at least approximately 17%.

High density array fabrication and readout method for a fiber optic biosensor

Patent Pinkel, Daniel [Walnut Creek, CA]; Gray, Joe [San Francisco, CA]; Albertson, Donna G [Lafayette, CA]

The invention relates to the fabrication and use of biosensors comprising a plurality of optical fibers each fiber having attached to its "sensor end" biological "binding partners" (molecules that specifically bind other molecules to form a binding complex such as antibody-antigen, lectin-carbohydrate, nucleic acid-nucleic acid, biotin-avidin, etc.). The biosensor preferably bears two or more different species of biological binding partner. The sensor is fabricated by providing a plurality of groups of optical fibers. Each group is treated as a batch to attach a different species of biological binding partner to the sensor ends of the fibers comprising that bundle. Eachmore »« less
