FBG technology is gaining popularity as an optical-fiber sensor for temperature or strain measurements due to its simple manufacturing process and robust reflected signal strength. Moreover, the wavelength-encoded nature of the output enables the use of the wavelength division multiplexing (WDM) technique, allowing each sensor to be assigned to a different wavelength range of the light source spectrum. Calibration plays a critical role in determining the sensor’s performance, and the ability to use WDM is a favorable feature contributing to the market’s growth.

Another key advantage of FBG sensors is their longer lifetime compared to other types of sensors. According to Hindawi, an open-access scientific journal publisher, life-prediction models suggest that FBG sensors in an unstressed condition can last around 56 years, while in stressful environments, such as FBG-based steel strands in their working environment, their estimated monitoring life is about 27 years.

FBG sensors offer several benefits over traditional monitoring devices in the construction and aviation sectors. However, challenges such as cost and technological limitations in certain use cases hinder their widespread adoption and growth.

The COVID-19 pandemic had a notable impact on the market. Initially, manufacturers faced difficulties in securing raw materials and components due to strict lockdown measures, causing disruptions in the global supply chain. However, as conditions normalize and major end-user industries expand their operations, the demand for FBG sensors is expected to grow during the post-COVID-19 period.

The temperature sensor segment holds the largest market value, reaching USD 227.4 million in 2022 and projected to reach USD 394.7 million by 2028, with a Compound Annual Growth Rate (CAGR) of 9.47% during the forecast period. Fiber Bragg grating (FBG) temperature sensors are strategically installed within industrial environments, including areas to be monitored and casting molds, where they are embedded directly into the hot casting zone. This enables distributed measurements in confined spaces, making FBG temperature sensors vital for production and industrial process monitoring in sectors like metal casting, chemical, and processing industries. FBG sensors are essential for enhancing production efficiency, reducing downtime and maintenance costs. Their appeal is further heightened by advancements in fiber optic sensing, enabling multiplexing of tens to hundreds of measurement points on a single optical line without compromising accuracy or reliability.

The aerospace segment currently leads the market in terms of value, standing at USD 222.2 million in 2022, and is expected to reach USD 392.8 million by 2028, exhibiting the highest CAGR of 9.81% during the forecast period. FBG sensors have demonstrated their suitability for various aerospace engineering applications, offering high precision, remote sensing capabilities, and lightweight characteristics. These sensors find extensive use in high-pressure sensing, ground-based aerodynamic test facilities, shock pressure sensing, spacecraft monitoring, and structural health monitoring of aircraft composites. Furthermore, FBG sensors are instrumental in airplane wing monitoring, fuselage fatigue analysis, and smart composite manufacturing for aircraft and space structures. Given the harsh and complex operating conditions in the aerospace industry, the selection of suitable sensors that can withstand extreme external environments while ensuring accuracy, reliability, precision, and repeatability is of paramount importance for industry players. Fiber optic technology configured with FBG sensors provides a dependable and lightweight solution for measuring and monitoring temperature along aircraft bleed air ducts, control valves, and critical areas.

Geographically, North America holds the largest market share of 37.57% in 2022 and is expected to reach USD 406.8 million by 2028. In contrast, the Asia-Pacific region is projected to witness the highest CAGR of 9.15% during the forecast period. The demand for FBG sensors in the Asia-Pacific region is driven by rapid industrialization in countries such as China, India, Japan, and South Korea. FBG-based sensors, including those for temperature, pressure, and strain, are extensively used in various process control industries such as water treatment, oil and gas, mining, and power generation. The growth of water and wastewater infrastructure in the region further boosts the deployment of FBG sensors. Governments in the region are actively supporting the manufacturing industry’s growth, creating additional opportunities for the FBG sensor market. For example, China has introduced measures to facilitate foreign investment in the manufacturing industry, enhancing trade and customs clearance processes. The Asia-Pacific region is home to some of the world’s largest power-generating countries, like Japan, India, and China, driving demand for FBG sensors in the power generation sector.

Recent Industry Developments

In February 2023, the UK government, in collaboration with the industry, made a significant investment of EUR 113 million (USD 120.65 million) in hydrogen and all-electric flight technologies. The primary objective of this investment is to pave the way for guilt-free flight options and to promote the creation of green jobs throughout the UK. As part of this initiative, a Bristol-based electric aircraft manufacturer, Vertical Aerospace, will undertake a project to develop advanced lightweight batteries. Additionally, Rolls-Royce will lead a project aimed at developing the foundational elements of a liquid hydrogen combusting jet engine, a crucial step towards enabling flights without carbon emissions.

In October 2022, the French government introduced its energy sobriety plan, which targets a 10% reduction in energy consumption by 2024. Through a comprehensive package of measures, the government aims to achieve a reduction of approximately 50 terawatt hours (TWh) per year in energy consumption. This plan also represents an initial stride towards achieving carbon neutrality, with the ultimate goal of attaining a 40% reduction in energy consumption by 2050. As a consequence of such developments, there is an anticipated increase in the demand for Fiber Bragg Grating (FBG) sensors, which will further bolster the growth of the FBG sensor market.
