▎ 摘　　要

NOVELTY - The sensor has an LCP substrate (1) fixed with a metal electrode (3). A graphene thin film layer (4) is formed with a graphite array layer (7). An upper surface of the LCP substrate is formed with an LCP thin film layer (2) that is formed with a hole way of an array structure. A gap is formed between a cover and the metal electrode. The metal electrode is selected from group consisting of gold, silver, copper, aluminum, platinum or titanium. Thickness of the LCP thin film layer is 25 to 50 micron. USE - Pressure piezo-resistive pressure sensor. ADVANTAGE - The sensor has high sensitivity and wide application range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a pressure piezo-resistive pressure sensor preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a pressure piezo-resistive pressure sensor.
