Latest Patents

Miaomiao Geng's latest patents include a "Method for preparing graphene modified composite planar pH sensor." This invention outlines a fabrication method for a composite planar pH sensor modified by graphene film. The process involves slotting into a substrate, setting copper foil on both sides, and applying leads on the copper foil. The graphene film is coated on the copper foils using a micro-mechanical stripping method to create the first and second graphene films. The method further includes depositing an Sb layer and SbO layer on the first graphene film by magnetron sputtering, followed by coating a Nafion™ perfluorinated sulfonic acid membrane on the SbO layer to fabricate the pH working electrode. Additionally, an Ag layer is deposited on the second graphene film, which is then dipped in FeCl solution to form an AgCl layer, followed by coating a third graphene film to create the reference electrode. This composite planar pH sensor is designed for pH measurement in solid, semi-solid, mash, and solution samples.

Another notable patent is the "Micro-nano textured graphene-based bionic pH sensor and preparation method therefor." This invention features a micro-nano textured graphene-based bionic pH sensor that includes a substrate, a working electrode, a reference electrode, and various copper contacts and leads. The design incorporates grooves in the substrate to house the working and reference electrodes, which are connected to inner leads via copper contacts. The working electrode consists of a graphene group and a sensitive electrode material layer, while the reference electrode includes a graphene group and a metal material silver layer. This pH sensor is capable of rapidly adsorbing water in soil and culture mediums, enabling in-situ pH measurement in heterogeneous systems.
