Optical fiber Bragg grating-based pressure sensor for soil monitoring applications

An optical-based pressure sensor for a 150 × 150 mm surface was designed and fabricated. The sensor utilizes a fiber Bragg grating (FBG) attached to a 30 × 30 × 30 mm actuator as the pressure sensing mechanism. The middle section of the actuator, which is circular, can bend into an elliptical form and, in the process, pull the FBGP via both ends when force or pressure is applied, thus converting the pressure applied to its surface into a wavelength shift. In laboratory testing, a sensitivity of 0.152 nm∕kPa was obtained. Subsequently, the pressure sensor was tested in the field by burying it 20 cm underground to measure soil pressure, while another FBG was spliced in series to the FBGP to compensate for temperature variations. Testing shows that the proposed design can realize a compact optical-based pressure sensor with enhanced soil monitoring applications such as dynamic soil pressure caused by soil movement.

“…The most common label-free integrated optical sensors are surface plasmon resonance (SPR) sensors [10], MZI sensors [11], grating sensors [12], etc. Although SPR sensing has been widely studied, and many research papers have demonstrated its excellent performance in biochemical sensing, its inherent size and miniaturization difficulties have limited its development and application.…”

“…A fiber Bragg grating (FBG) is a passive optical fiber device with narrow band reflection characteristics fabricated on an optical fiber. Because of its small size, large measurement range, good wavelength selectivity, insensitive polarization, and strong anti-interference ability, FBGs are widely used in many fields such as infrastructure, national defense and security, biomedicine, and petrochemicals [1][2][3][4]. The numbers of sensors required in such applications have also been increased significantly to ensure that the accuracy of sensor data monitoring does not decrease.…”

In this study, a new square-based fiber Bragg grating (FBG) sensor network model is proposed to address possible link failures in FBG sensor networks and improve their reliability. Graph theory and optical switching are simultaneously applied to these sensor networks to improve their self-healing ability; the FBG sensor network is regarded as a directed graph. Three commonly used self-short-circuit algorithms are compared in terms of the self-healing capabilities that they provide to the optical fiber sensor network. Among these, the shortest-path faster algorithm achieved a high, nearly 90% repair accuracy and had an average repair time of 0.103 s, the shortest in this study. The newly designed FBG self-healing network can be reorganized and repaired when local damage occurs, thereby improving its reliability.
