Abstract

The invention discloses a manufacturing method for an optical fiber sensor. The optical fiber sensor comprises a substrate body, polymer gel and a functional sensor. The manufacturing method comprises the following steps that a) substrate material is flatly laid on a flat plate, and then the polymer gel is adhered to the substrate material in an aligned manner; b) the functional sensor is straightened out and embedded in the substrate material, and then the substrate material is flatly laid on the functional sensor to be ironed by a temperature-regulating electric iron; c) the ironed optical fiber sensor is placed in a press vulcanizer to be hot-pressed for 2-4 hours under the curing pressure of 1-3 MPa and the hot-pressing temperature of 105-180 DEG C; d) the optical fiber sensor is water-cooled to reach room temperature, and the sensor is taken out. The polymer gel is prepared by compounding TiO2 with N, N-methyl benzene acryloxyethyl with different concentrations as the cross-linking agents. According to the manufacturing method, the compounding operation is easy and feasible, and the prepared intelligent optical fiber material has good stability and sensitivity.

Description

technical field [0001] The invention relates to a manufacturing method of a sensor, in particular to a manufacturing method of an optical fiber sensor. Background technique [0002] In recent years, sensors are developing in the direction of sensitivity, precision, adaptability, compactness and intelligence. In this process, fiber optic sensors, a new member of the sensor family, are favored. Optical fiber has many excellent properties, such as: anti-electromagnetic interference and atomic radiation performance, thin diameter, soft and light mechanical properties; electrical properties of insulation and non-induction; chemical properties of water resistance, high temperature resistance and corrosion resistance, etc. It can play the role of human eyes and ears in places that people can't reach (such as high temperature areas) or areas that are harmful to people (such as nuclear radiation areas), and it can also go beyond human physiological boundaries and receive human senso...
