Jing-Jay CHIU 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).

  • Gas sensor and manufacturing method thereof, and gas sensing system
    Patent number: 11378549
    Abstract: A gas sensor comprises a basic part and a sensing layer deposited on the basic part. The basic part includes a circuit board and at least one surface acoustic wave element disposed on the circuit board. The sensing layer is a nanocomposite film of reduced graphene oxide/tungsten oxide/polypyrrole deposited on the surface acoustic wave element. The sensing layer combines reduced graphene oxide, metal oxide, and conductive polymer, so that the sensing layer is able to perform sensing at room temperature, and can be more sensitive. The present invention provides a method for manufacturing a gas sensor, and a gas sensing system including the gas sensor.
