How to test the piezoelectric ceramic?

In He Shuai company, we did 100% testing report for every piece. No matter what you placed it order with 1 pcs or hundreds thousands. Making sure of that every products are 100% high quality. Then,our QC department is getting more important in this production processing. How can we test it?

  1. Machine: Impedance Analyzer
  2. We first calibrate analyzer by open-short and 50 Ohl load in related frequency range. Then we’ve made automatic measurements of IZI, Teta, Conductance, Reactance, Susceptance etc. We’ve found resonace frequecies and  draw smith chart etc…
  3. For example: 2Mhz, HIFU piezo ceramic

We need adjust the machine frequency from 1.5Mhz to 3Mhz.

That’s very important setting. Don’t set it wrong ways. Like : 1Mhz to 2Mhz.

Or 2Mhz to 3Mhz. Make sure your frequency is within your setting range.

See the picture as below:

Attention for testing piezo ceramic

The bundle includes a Piezoelectric Displacement Sensor, Heated Piezoelectric/Pyroelectric Measurement Test Fixture, and Advanced Piezoelectric Software. The Bulk Piezoelectric/Pyroelectric Test Bundle allows samples to internally be heated to 230C in a self-contained test fixture. The heating unit is built-in to the sample holder, so no additional temperature chamber is necessary. The bundle’s simple user interface is controlled by Radiant’s fully automated Vision Data Acquisition Software

  1. the Bulk Piezoelectric Test Bundle is a cost effective option for researchers measuring piezoelectric displacements on the order of one micron or larger using Radiant testers.  The high voltage displacement test fixture provides a safe operating environment for testing at high voltages and is rated to 10kV. The fiber optic sensor detects the amplitude of non-coherent light reflected from the sample surface to determine the distance from the sensor wand to the sample surface.
