Abstract
A gas sensing device comprises a silicon substrate, an insulating layer, a plasma treatment layer, a metal electrode and a sensing layer. The insulating layer is formed on the silicon substrate. The plasma treatment layer is formed on the insulating layer. The metal electrode is formed on the portion of the plasma treatment layer. The sensing layer is formed on a surface of the metal electrode and the plasma treatment layer. Through plasma treatment for the substrate and printing graphene film on the substrate and the electrode, the adsorption characteristics of gas selection ratio for graphene is improved, and the processing time of the plasma treatment is adjusted to optimize the sensing characteristics.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
