In the past few decades, the application of optical fiber has infiltrated a number of subject areas. Optical fiber anti-electromagnetic interference, remote monitoring, multiple monitoring, small size and light weight and other characteristics, making it in the field of sensor research concern. Since the birth of optical fiber sensor with self-assembled polyelectrolyte layer self-assembled film has been developed in 2000, it has become a new research hotspot in sensor field. This type of optical fiber sensor has a wide range of applications in the monitoring of trace substances. Based on the advantages of optical fiber and optical fiber sensors, this paper summarizes the types, properties, detection principles and corresponding optical fiber structures and self-assembly materials of optical fiber sensors based on multi-layer self-assembled multilayer films. Self-assembly of polyelectrolyte layers on optical fiber substrates and testing of self-assembled film-based optical fiber sensors; Focusing on fiber pH sensors, humidity sensors, gas sensors, biosensors and other types of optical fibers Sensor preparation and application, and prospects for the future development of polyelectrolyte layer self-assembled multilayer film optical fiber sensor.
