▎ 摘　　要

NOVELTY - The pressure sensor has a flexible water-resistant nanopaper (9). A graphene film (1) is provided on one side of the flexible nanopaper. The thickness of the water-resistant nanopaper is from 20 mu m to 100 mu m. The graphene film is provided with three to ten graphene or preferably one to three graphene sheets, where each of the sheets is a self-assembled layer of graphene powder formed by deposition. A pair of electrodes (2) is connected to two ends of the graphene film that are opposite to each other in a longitudinal direction of the graphene film. The pair of electrodes is conductive copper tape or conductive silver wire. USE - Pressure sensor attached to skin surface of user for determining pulse of user, for use in pressure detecting device for detecting sound vibration (all claimed), used in practical applications such as diagnostics and therapeutics. ADVANTAGE - The use of the pressure sensor improves accuracy of the detection results and the sensitivity of the detection device. The pressure sensor is user-friendly, convenient and biocompatible to reduce the risk of allergic reactions. The configuration of the electrodes improves conductivity and the accuracy of the resistance measurements. The pressure sensor is provided with sufficient strength, while still allowing deformations in the sensing element to be transmitted with high sensitivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a pressure detecting device; and (2) a method of fabricating pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the pressure detecting device. Graphene film (1) Electrodes (2) Resistance detecting unit (3) Flexible nanopaper (9)
