Patents by Inventor Samuel K. Kassegne

Samuel K. Kassegne has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11877851
    Abstract: A probe device is disclosed that includes one or more insulating layers and a glassy carbon layer. The glassy carbon layer includes one or more channels. Each channel includes a microstructure, which may include an electrode region, interconnect region, and bump pad region. The electrode region may be placed in contact with a human or animal patient or test subject and used to collect or deliver signals in applications such as electrocorticography (ECoG), electromyography (EMG), and neural stimulation. A method of making a probe includes depositing a glassy carbon precursor on a substrate, patterning the precursor using photolithography, pyrolyzing the precursor to allow the formation of glassy carbon, and depositing one or more insulating layers.
    Type: Grant
    Filed: August 30, 2018
    Date of Patent: January 23, 2024
    Assignee: San Diego State University Research Foundation
    Inventors: Samuel K. Kassegne, Surabhi Nimbalkar, Arvind Balasubramani
  • Publication number: 20230223207
    Abstract: A meta-material is disclosed that includes a first layer composed of graphene, and one or more additional layers, each composed of glassy carbon or graphene. A method of producing an engineered material includes depositing a graphene precursor on a substrate, pyrolyzing the graphene precursor to allow the formation of graphene, depositing a glassy carbon precursor the graphene, pyrolyzing to allow the formation of glassy carbon from the glassy carbon precursor, depositing a graphene precursor on the glassy carbon, and pyrolyzing the graphene precursor to allow the formation of graphene.
