▎ 摘　　要

NOVELTY - The device has a first graphene layer coupled to a first electrode of a key for storing multiple first charges. A second graphene layer is coupled to the second electrode of the key, and stores multiple second charges. The first graphene gel layer is provided with multiple holes for storing an ionization carrier. A pressure detector is fixed below the graphene layer under the gas gel layer, and is connected to a controller for detecting a pressing. A graphene electrode is connected with a contact gel for receiving the first charges from the ionizing carrier. The contact gel receives the second charges from the ionization carrier, where the first and second charges are opposite in polarity. USE - Input interface device i.e. computer keyboard, for inputting data in a computer system. ADVANTAGE - The input interface device enhances the operational efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an input interface device (Drawing includes non-English language text). 2Input interface device 20Controller 21Keystroke 26Processor 212Insulating layer 213Graphene gel 215Electrode 217Electrode 219Pressure detector
