Abstract
In this paper, the characteristics of the high birefringence fiber (HBF) strain sensor based on piezoelectric ceramic have researched, and analyzed with the force of piezoelectric ceramic because the voltage applied on HBF and the force of the HBF wounded on the piezoelectric ceramic. We can get the relationship between the applied voltage and the shift of the trough wavelength by calculating the equation of the shift of birefringence and trough wavelength, at the same time, compared the experimental with fitting curves and the difference between elliptical fiber and panda fiber. Then connect the fiber sensing experiment based on the piezoelectric ceramic with the fiber temperature sensing experiment, and change the temperature and the stress individually. Lastly analyze the results of the joint experiments.
