【Abstract】 Piezoelectric strain constant d 33 is one of the important parameters of piezoelectric elements Based on the converse piezoelectric effect of the piezoelectric elements and the definition of d 33 , a new method ( E-S Method) is provided to measure d 33 The values of piezoelectric strain constant d 33 of piezoelectric ceramics are measured with experiments A comparison between the testing results from E-S method and those of quasi static method is made. The results show that E-S method has high precision更多还原
