This paper describes steps involved in the design and realization of a new type of pressure sensor based on the optical fiber Bragg grating. A traditional pressure sensor has very limited usage in heavy industrial environments, particularly in explosive or electromagnetically noisy environments. Utilizati...
pressure sensorfiber Bragg grating (FBG)axial forceBased on the principle of the fiber Bragg grating, a new type of fiber-optic pressure sensor for axial force measurement of transformer winding is designed, which is designed with the structure of bending plate beam, the optimization of the ...
A high-sensitivity and small-size pressure sensor based on dual fiber Bragg grating (FBG), a diaphragm and hinge-lever structure is proposed. Its measurement principle is described and simulation analysis is conducted. We compensate for temperature cross-sensitivity by using an additional FBG to acc...
A fiber Bragg grating (FBG) sensor was used to monitor the early age curing temperatures of cement paste. Additional advantages in using the sensor were highlighted. The FBG was inscribed by a Continuous Wave 244 nm argon ion laser in the photosensitivity fiber. The fabricated FBG was calibrated...
Fig. 1. Sensing principle of fiber Bragg-grating sensor. 2.2. Design and fabrication process A detailed view and the three-layer structure of the proposed hybrid transducer is displayed in Fig. 2b. The upper circular diaphragm I, used to measure the overburden earth pressure, was set with a...
This paper presents a novel and high-sensitivity optical tactile sensor array based on fiber Bragg grating (FBG) to explore and localize tissue abnormalities during tissue palpation in a minimally invasive surgery. This sensor consists of five separate tactile cells with the same configuration, associa...
Acoustic emission (AE) during a pressure test of a carbon fiber-reinforced plastic tank was measured using a fiber Bragg grating (FBG) sensor and, for comparison, using a conventional piezoelectric sensor. The FBG-inscribed optical fiber was used not only as an optical transmission line but also...
To offset the lack of tools capable of efficiently monitoring local and dynamic contact conditions relating to stress and heat simultaneously, a sensor using a waveguide Bragg grating has been developed and tested thermomechanically. We demonstrate that temperature and strain measurements inside transparent...
In this study, an environmental acrylonitrile butadiene styrene (ABS) resin was combined with three-dimensional (3D) printing technology to develop a new pressure sensor body with the molding pressure for fiber Bragg grating (FBG) sensor technology embedded in the sensor body. The production of the...
