Abstract: A sensing apparatus that includes a plurality of sensing pixels is provided. The sensing pixels are arranged in an array, and each of the sensing pixels includes an active device and a sensing device. The sensing device is electrically connected to the active device, and the sensing device includes a first electrode layer, an amorphous silicon layer, a second electrode layer, and a graphene layer. The amorphous silicon layer is located on the first electrode layer. The second electrode layer is located on the amorphous silicon layer and has an opening. The graphene layer is in contact with the second electrode layer and the amorphous silicon layer.

Abstract: A method for manufacturing nano-graphene sheets, includes: intercalating and oxidizing a graphite material to form a graphite oxide by mixing the graphite material with an intercalation agent and oxidant; contacting the graphite oxide with a heat source to thermally flake the graphite oxide to nano-graphite sheets; suspending the nano-graphite sheets in a liquid medium and applying a mechanical shear force larger than 5,000 psi to mechanically flake the nano-graphite sheets for reducing the lateral size and thickness to form a nano-graphene suspension solution; separating the nano-graphene sheets from the nano-graphene suspension solution and drying the nano-graphene sheets; and finally reducing and heat treating the nano-graphene sheets to lower the oxygen content to less than 3 wt % and decrease the crystal defects.

Abstract: The present invention discloses a complex epoxy resin adhesive added with carbon nanotubes, and the complex epoxy resin adhesive can be prepared in advance and then stored at room temperature. When use, the preheating step is no longer required anymore, and the complex epoxy resin adhesive mixed with carbon nanotubes is coated uniformly onto an adhering position, and microwave is used for heating and curing the adhesive, so as to achieve the dual effects of surpassing the enhanced curing property of a simple epoxy resin and reducing the curing time.

Abstract: A computer system includes a main processor, a display device, and a touch screen. The main processor is configured to execute instructions and to carry out operations associated with the computer system. The display device is electronically coupled to the main processor, for displaying a graphical user interface. The touch screen is electronically coupled to the main processor. The touch screen includes at least two modes among a touch-screen keyboard mode, a multi-touch screen mode, and a multi-touch screen plus keyboard mode.
