Frédéric LOIZEAU 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: 10261046
    Abstract: Disclosed are improved methods and structures for electrochemical sensors that may advantageously sense/detect chemical species including pollutants and/or energetics in a gaseous phase. Sensors according to the present disclosure may advantageously be fabricated using large scale microfabrication techniques and materials.
    Type: Grant
    Filed: January 9, 2017
    Date of Patent: April 16, 2019
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: Beth L. Pruitt, Thomas Jaramillo, Tom Larsen, Frédéric Loizeau, Pierre-Alexandre Gross

  • Patent number: 9506822
    Abstract: A double-side-coated surface stress sensor includes a sensing membrane structure portion where at least two ends opposite each other are fixed on a mounting portion; a receptor layer that coats both surfaces of the sensing membrane structure portion; and an element detecting a stress, which is provided in the vicinity of at least one of the fixed two ends, opposite each other, of the sensing membrane structure portion or at least one of the fixed two ends, opposite each other, of the mounting portion, in which in a detection output is obtained from the element based on the stress which is applied onto the receptor layer coating both of the surfaces of the sensing membrane structure portion. Accordingly, it is possible to provide a double-side-coated surface stress sensor which coats both surfaces of the sensing membrane structure portion by the receptor layer, thereby obtaining a sufficiently large detection output.
