Polyimide-Coated Fiber Bragg Grating Sensors for Humidity Measurements

Humidity is one of important environmental parameters, which refers to the water vapor content in the air. As one of the fundamental abiotic factors, humidity determines an environment where animals and plants can thrive, also influences the human life. There are three items commonly used to describe humidity, which are absolute humidity (AH), relative humidity (RH) and specific humidity (SH) [...

Strain Measurement of Composite Laminates Using Fiber Bragg Grating Sensors

Fiber Bragg grating(FBG) sensors, one of the fiber optic sensors(FOS), based on the wavelength division multiplexing(WDM) technology are ideally suitable for structural health monitoring of composite materials and structures. Proper monitoring of measurands in FBG sensor systems requires accurate measurement of the Bragg center wavelength, and the ability to track rapid shifts of the wavelength...

Detection, Localization and Quantification of Impact Events on a Stiffened Composite Panel with Embedded Fiber Bragg Grating Sensor Networks

Nowadays, it is possible to manufacture smart composite materials with embedded fiber optic sensors. These sensors can be exploited during the composites' operating life to identify occurring damages such as delaminations. For composite materials adopted in the aviation and wind energy sector, delaminations are most often caused by impacts with external objects. The detection, localization and ...
