Piezoelectric Ceramic Characteristics Using Fiber Grating Sensor
A method for characteristics of piezoelectric ceramics was presented using a fiber Bragg grating sensor.An unbalanced Michelson interferometer was utilized to demodulate the fiber Bragg grating sensor signals.The relationship between the displacement of piezoelectric ceramic and the applied voltage was shown by observing the phaseshift induced by wavelengthshift.The hysteretic and creep properties of the piezoelectric ceramic were demonstrated experimentally,and the applied voltagedisplacement curve and the creep curve were obtained.The results show that the fluctuations of light power had no effect on hysteretic,and the voltage direction has nothing with creep.
