Abstract: A display device includes a display panel in which an active area and a peripheral area are defined, and an antenna unit including a main pattern, a first sub-pattern, and an antenna line. The main pattern is disposed on the display panel in the active area, transmits and/or receives a signal, and operates at a first frequency. The first sub-pattern is disposed on the display panel in the active area, is spaced apart from the main pattern in a first direction, is capacitively coupled to the main pattern, and operates at a second frequency different from the first frequency.

Abstract: A method for manufacturing a charge pump-based artificial lightning generator comprises the steps of: forming a second electrode on a prepared substrate; forming a negatively charged body having a sponge structure under the second electrode; removing spherical polymer particles from the negatively charged body using a toluene solution; allowing metal particles to penetrate into the negatively charged body; forming a positively charged body in a location which is at a predetermined distance below the negatively charged body in order to generate charges; nano-structuring the surface of the positively charged body; coating the nano-structured surface of the positively charged body with second metal particles; forming a ground layer for charge separation while maintaining a constant distance in the downward direction from one side of the positively charged body; and forming a first electrode for charge accumulation in a location which is at a predetermined distance below the positively charged body. Accordingly, the present invention can be miniaturized, can produce high-output energy from minute energy such as a wind, a vibration, or a sound, and can remarkably reduce costs incurred according to energy collection.

Abstract: A bio sensor using electromagnetic waves according to an embodiment may comprise a resonator assembly, a power supply unit, and a processor. The resonator assembly may include at least one feeding line which is disposed along the outer edge of a feeding area and can feed electric power to the feeding area, and a pattern wire which is disposed along a pattern in the feeding area and can receive electric power from the feeding line through capacitive coupling. The power supply unit may supply electric power to the resonator assembly. While a frequency of the electric power is swept, the processor may acquire a parameter which is biometric data corresponding to a concentration of a target analyte existing around the resonator assembly and is related to a resonant frequency of the resonator assembly.

Abstract: The present disclosure relates to a bismuth vanadate electrode including vanadium-functionalized graphene quantum dots and a method for preparing the same. More particularly, it relates to a technology which is capable of, by adding graphene quantum dots (GQDs) in the process of immersing a bismuth vanadate (BiVO4) electrode in an alkaline solution to remove vanadium oxide (V2O5) excessively formed on the surface of the electrode during its preparation, protecting the electrode from the alkaline solution as the graphene quantum dots are adsorbed onto the surface of BiVO4 while V2O5 is removed, and improving the efficiency of oxygen evolution reaction (OER) when applied to a photoanode due to vanadium (V)-functionalized graphene quantum dots formed as the etched vanadium ions ((VO)43−) are adsorbed onto the graphene quantum dots.
