Fiber Bragg Grating Sensor Market Size (2024 - 2029)

Fiber Bragg Grating Sensor Market Analysis

The Fiber Bragg Grating Sensor Market size is estimated at USD 0.76 billion in 2024, and is expected to reach USD 1.16 billion by 2029, growing at a CAGR of 8.83% during the forecast period (2024-2029).

• Fiber Bragg grating (FBG) technology is becoming a popular choice for optical fiber sensors for temperature or strain measurements because of their simple manufacture, relatively strong reflected signal strength, and operational flexibilities.
• A periodic modulation of the refractive index of the fiber core along the longitudinal direction forms fiber Bragg grating sensors. Various sensing functionalities can be added to the optical fiber by carefully determining the structure. The wavelength-encoded nature of the output allows the use of the wavelength division multiplexing (WDM) technique by assigning each sensor to a different wavelength range of the available light source spectrum. As calibration is used to determine the mapping relationship between the physical quantity and wavelength and is one of the critical factors affecting the sensor's performance, such a feature favors the market's growth.
• Furthermore, a longer lifetime than other sensors is another major factor supporting the market's growth. According to Hindawi, a publisher of peer-reviewed, open-access scientific journals, the life-prediction model indicates that the estimated monitoring life of an FBG sensor in an unstressed condition is about 56 and 27 years under the stressful situations that fiber Bragg grating (FBG)-based steel strands are subjected to in their working environment.
• Owing to their intrinsic capability to measure a variety of parameters, such as strain, pressure, temperature, and many others, along a single fiber, their demand has been increasing across various end-user industries. Additionally, these multi-point sensing arrays of many relatively low-cost FBGs also provide great flexibility of design, making them ideal devices to be adopted for a multitude of different sensing applications.
• Fiber Bragg grating sensors have many advantages over traditional and structural monitoring devices in the building and aviation sectors. However, cost and technological limitations in some use cases are among the significant factors challenging their widespread adoption and growth.
• A notable impact of the COVID-19 pandemic was observed in the market studied. During the initial phase, the manufacturers faced difficulties in securing the supply of raw materials/components due to stringent lockdown measures, which disrupted the supply chain globally. However, with the condition normalizing and major end-user industries expanding their operations further, the demand for these sensors is expected to grow during the post-COVID period.
