Reviewing the Role of Fiber Bragg Grating Temperature Sensors in Smart Factories: Opportunities and Challenges

In this paper, we review the role of Fiber Bragg Grating (FBG) sensors for temperature monitoring and their application in the smart factories. In the first instance, we present the historical context and fundamental principle of FBG based sensors. Then, we review of recent development in FBG temperature sensors. We explore the use of FBG sensors in industry 4.0, specifically in smart factories, and offer a few ideas that might possibly open up a lot of doors for the development of fiber Bragg grating sensors.
