I think you should give more details about your question. Because there are many methods to measure that. Are you planning to measure bulk material or thin film or nano objects? IF it is nano check thisl ink : http://pubs.acs.org/doi/abs/10.1021/nn503269b  or this https://www.researchgate.net/publication/264865919_Spontaneous_High_Piezoelectricity_in_Poly%28vinylidene_fluoride%29_Nanoribbons_Produced_by_Iterative_Thermal_Size_Reduction_Technique

If you write details of your experiment plans, i could help you better.

Best,

Mehmet.

Piezoelectric Ceramics Characterization

Thanks every one

you can trying making a BZT-BCT ceramic by conventional solid state reaction, and pole it.  It can yield quite d33 values.

Hi,

Please have a look

Article Atomic-scale origin of piezoelectricity in wurtzite ZnO

The piezoelectric constant, d33, is measured using a Berlincourt D33 meter.

The sample is placed in the jaws of the instrument and the d33 is read out directly.

The sample thickness doesn't matter (I've used 2 um and as thick as 1 cm). A calibrated mechanical vibration is input and charge is measured. d33 is simply the charge over the amplitude of the force from the vibration source. You don't even need electrodes on the sample; the instrument jaws are the electrodes.

The piezoelectric constant, d33, being higher or lower depends on whether you are converting pressure to volts or volts to pressure. Pressure to volts is better with high d33. Volts to pressure is better with low d33. In other words, a receiver needs high d33 and a transmitter needs low d33.

The simplest method to measure a piezo electric transducers is to stress the material with a specific pressure and measuring the charge by using Keithley charge meter. The pressure can be applied by a specific weight on the area of the sensor. Using Keithley is important since it had a very high input impedance enabling to measure the charge with high accuracy.
