Comparison of Methods for the Measurement of Piezoelectric Coefficients

IEEE Transactions on Instrumentation and Measurement, 2013
The charge constant of piezoelectric material is one of the crucial constant values. At the present time, the measurement of this value is mostly realized by means of three techniques: the frequency method, the laser interferometer technique, and the quasi-static method.
