“…In 2010, Chen et al reported a curvature sensor based on Bragg gratings carved in an eccentric-core POF that can measure the magnitude and orientation of the applied bend [24]. In particular, with the development of POF, more and more research has been reported in the field of high-sensitivity sensors and lasers [25,26]. The fiber optic sensor used as temperature monitoring is mainly based on its unique advantages of antielectromagnetic interference, high stability, and ability to be used in a harsh environment [27,28].…”
