ABSTRACT:
The invention is a pressure sensing device utilizing a polymer optical fiber with a core comprised of a flexible thermoplastic aliphatic segmented polyurethane. The use of an optical fiber based pressure sensor eliminates the electromagnetic interference problems associated with conventional electronic pressure sensors. Use of polyurethane as the core material for the optical fiber results in an optical fiber with high flexibility, thus making the inventive pressure sensing device more rugged and durable than other optical fiber based pressure sensors.
