With the continuous development of optical fiber sensing technology, fiber Bragg grating (FBG) vibration sensor has become more and more excellent in the performance of complex vibration measurement in practical applications. Based on the advantages of FBG vibration sensor, the working principle of FBG vibration sensor is described briefly, and the advantages and disadvantages of some cantilever beam, diaphragm and hinge structures developed in China in the past 5 years are introduced. Finally, four suggestions for FBG vibration sensors are put forward, and the development direction of FBG vibration sensors is prospected.
