    Abstract: There is disclosed a surface micromachined (MEMS) gyroscope device where the resonance frequencies are capable of being adjusted and tuned for obtaining maximum response gain for higher sensitivity. The MEMS gyroscope comprises of a substrate (1), a proof-mass (2), a capacitive area-changed plate (3), a driving mode electrode (4) and a sensing mode electrode (5). The proof -mass (2) is structured as a cross-shaped body that includes the sensing mode and driving mode electrodes (4, 5) where the proof -mass is adapted to oscillate back and forth laterally over the capacitive area-changed plate (3) defining an area-changed capacitive type MEMS gyroscope. The driving and sensing mode electrodes (4,5) are shaped as a symmetrical branch-finger structure. The proofmass is connected to the substrate (1) through a spring (6) and the branch-finger structure is provided having two different gap side-by-side and narrow-wide narrow gap series configuration, whereby, the spring is configured as a circular-shaped, rectangular-shaped or variations of the same. The spring constant {K X , K y ) is controllable and adjustable through the application of voltage on the branch finger acting as actuator and pseudo spring thus providing tuned resonant frequency for higher sensitivity.

    Abstract: The present invention relates to a method for preparing a graphene-based inkjet ink characterised by the steps of: exfoliating graphene oxide (GO) in deionised water at 25 - 30°C (100); reducing the GO and silver nitrate (AgNOs) at 25°C to 30°C to form a reduced GO (rGO) and silver (Ag) mixture (200); reacting the rGO and Ag mixture to form a rGO/Ag nanoparticles (rGO/Ag-NPs) mixture (300) without agitation at 25°C to 30°C; sonicating the rGO/Ag-NPs mixture (400) at 65°C to 68°C; centrifuging the rGO/Ag-NPs mixture to produce the graphene- based colloidal solution (500); and dispersing the graphene-based colloidal solution in a dispersant solution to produce the graphene-based inkjet ink (600).
