Paper Abstract

We demonstrate the application of a fiber Bragg grating based sensor system as a distributed pressure sensing catheter for the human esophagus. It allows space-time resolved measurements of the peristaltic waves of the gullet. The sensor system comprises 30 fiber-optic pressure sensors in a single fiber with a spatial distance below 10 mm each. The sensors are fiber Bragg gratings that are manufactured during the drawing process of the fiber and therefore show enhanced mechanical stability compared to fiber Bragg gratings with local recoating. A well designed soft plastic coating wand will be used to convert local pressure variations into strain variations of the optical fiber core.
