WEI-YIN ZENG 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).

  • Capacitor-based fluid sensing units and operating methods thereof
    Patent number: 10551340
    Abstract: The present invention provides capacitor-based fluid sensing units. The capacitor-based fluid sensing unit comprises a substrate, a first electrode configured on the substrate, a sensing layer configured on the first electrode, a second electrode configured on the sensing layer. More particularly, the second electrode is a porous electrode, while the sensing layer is made of a porous dielectric material and has a thickness between 50 nm and 5 mm. Permittivity of the sensing layer changes as fluid permeates from the second electrode to the sensing layer. The subsequent change in capacitance of the capacitor-based fluid sensing unit is used to determine the volume of the fluid.
