Abstract

A new instrument for measuring piezoelectric coefficients has been developed. The principle of this instrument is simple, namely, applying a uniaxial stress to a sample and measuring the induced charge. The stress applied to the sample is measured as an electric signal. The main part of the instrument is shaped like a small probe with an electrode at the tip for measuring the charge, and piezoelectric coefficients can be measured easily and quickly by pressing the probe on samples by hand. The piezoelectric coefficient d₃₃ of ferroelectric Ba_1-xLa_xTi_1-xCr_xO₃ ceramics were measured using the probe, and it is revealed that the compound shows a maximum d₃₃ of 70 pC/N when x is approximately 0.014-0.018.
