Pressure Membrane FBG Sensor Realized by 3D Technology. [PDF]

open access: yesSensors (Basel), 2021
The publication describes the design, production, and practical verification of an alternative pressure sensor suitable for measuring the pressure of gas, based on a combination of fiber-optic technology and 3D printing methods. The created sensor uses FBG (Fiber Bragg Grating) suitably implemented on a movable membrane.

Enhanced Strain Measurement Range of an FBG Sensor Embedded in Seven-Wire Steel Strands [PDF]

open access: yesSensors, 2017
FBG sensors offer many advantages, such as a lack of sensitivity to electromagnetic waves, small size, high durability, and high sensitivity. However, their maximum strain measurement range is lower than the yield strain range (about 1.0%) of steel ...

Measurement of Pulse Wave Signals and Blood Pressure by a Plastic Optical Fiber FBG Sensor [PDF]

open access: yesSensors, 2019
Fiber Bragg grating (FBG) sensors fabricated in silica optical fiber (Silica-FBG) have been used to measure the strain of human arteries as pulse wave signals. A variety of vital signs including blood pressure can be derived from these signals.

Multipeak Treatment of FBG Sensor Signal

open access: green, 2014
Fiber Bragg Grating (FBG) sensors are increasing their importance in Structural Health Monitoring (SHM) of composite materials. They excel at reduced size, electromagnetic immunity and corrosion resistance. Furthermore, they are sensitive to strain and temperature, allowing the record of both parameters simultaneously.

FBG laser sensor with PS [PDF]

open access: yesElectronics Letters, 2018
Owing to unstable multi‐wavelength lasing, robust measurement is difficult with a fibre Bragg grating (FBG) laser sensor system that uses FBGs as laser cavity mirrors as well as sensors. A stabilising technique is essential for proper data acquisition.

Fiber Bragg Grating Pressure Sensor Integrated with Epoxy Diaphragm

open access: yesSensors, 2021
A fiber Bragg grating (FBG) sensor integrated with an epoxy diaphragm was developed for the measurement of pressure and water level. The bending strain of a circular diaphragm induced by uniform pressure was transferred to the FBG sensor. The response of
