Design, fabrication and characterization of high temperature piezoelectric vibration sensor using YCOB crystals

Journal Article


Abstract


  • A shear-mode piezoelectric accelerometer using YCa4O(BO3)3 single crystals (YCOB) was designed, fabricated and successfully tested for high temperature vibration sensing applications. Dynamic modeling

    of the accelerometer was presented first, followed by YCOB single crystal sample preparation, sensor

    assembly and experimental setup establishment. The prototyped accelerometer was tested at temperatures ranging from room temperature to 1000 ◦C and at frequencies ranging from 50 Hz to 350 Hz. The

    sensitivity ofthe prototype was found to be 5.9 ± 0.06 pC/g throughoutthe tested frequency,temperature

    and acceleration ranges. In addition, YCOB piezoelectric accelerometers retained the same sensitivity at

    1000 ◦C for a dwell time of 9 h, exhibiting a high stability and reliability
