FIBER OPTIC PRESSURE SENSOR Russian patent published in 2017 - IPC G01L11/02 

FIELD: measuring equipment.

SUBSTANCE: fiber optic pressure sensor contains an optical fiber, a radiation receiver. Around the optical fiber there are electrically luminescent and radially polarized piezoelectric concentric cylindrical layers, internal and external electrodes with varying control voltage are introduced. The inner electrode is transparent and is installed between the optical fiber and the electroluminescent layer, and the outer electrode is mounted around the piezoelectric layer.

EFFECT: increase in the working surface of the fiber, the determination of the distribution function of the inhomogeneous pressure along the entire length of the fiber, and the location of the zones of increased pressure.
