Flaechiges Hochtemperatur-Drucksensorarray und Druckmessverfahren zur Bestimmung von Druckverteilungen sowie Verwendung derselben

(A1) Die vorliegende Erfindung bezieht sich auf einen flaechigen Hochtemperatur-Drucksensor zur Bestimmung einer Druckverteilung in der Sensorflaeche (S) aufweisend eine obere Deckschicht (1), eine untere Deckschicht (2) und mindestens eine zwischen der oberen und der unteren Deckschicht eingebettete und/oder einlaminierte, mindestens ein Faser-Bragg-Gitter (4) aufweisende Lichtleitfaser (3).

DE 102008059856 A1 UPAB: 20100624 NOVELTY - The laminar high temperature pressure sensor has an upper surface layer (1), a lower surface layer (2) and an optical fiber having fiber Bragg lattice embedded or laminated between upper surface layer and the lower surface layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a pressure measuring method for determination of pressure distribution in a surface. USE - Laminar high temperature pressure sensor for determination of pressure distribution in the sensor surface. Can also be used for an object, particularly a laminar object, and for transfer molding, injection molding, chip capping during wafer bonding (all claimed). ADVANTAGE - The optical fiber has a fiber Bragg lattice embedded or laminated between upper surface layer and the lower surface layer, and hence ensures determination of pressure distribution in reliable manner with high accuracy and small susceptibility to interference with higher temperatures.
