Sensitization type flexible optical fiber pressure sensor

The utility model relates to a sensibilization type flexible optical fiber pressure sensor, belonging to the optical fiber pressure sensor technology field, the sensibilization type flexible optical fiber pressure sensor comprises a sensor body, the sensor body comprises a contact table, a thin film layer and an optical fiber penetrating in the thin film layer, the contact table is arranged on the top of the thin film layer, the bottom of the thin film layer is provided with a groove, and the contact table is arranged in the groove. By adopting the structure, the bottom of the thin film layer is provided with the groove which is aligned with the position of the contact table, so that the supporting effect of the thin film layer on the contact table is weakened, normal pressure downwards acts on the contact table, the supporting force of the thin film layer on the contact table is reduced, and the stress strain constraint of the sensor body is reduced; therefore, the sensor body can generate larger deformation
