THE STUDY ON MECHANIC-ELECTRICAL PROPERTIES OF CEMENT-BASED PIEZOELECTRIC CERAMIC COMPOSITE

摘要

In this paper,the study of mechanic-electrical response of cement-based piezoelectric composite is presented. A linear relationship of mechanicelectrical response of the composite is obtained according the constitutive piezoelectric equations. The experimental results are consistent with the relationship very well. The study shows that cementbased piezoelectric composite is suitable for potential application as dynamic mechanical sensor with excellent dynamic response and high static stability.
