Theoretical analysis of the dynamic properties of 2–2 cement based piezoelectric composite for sensor applications

Till now only a few of literatures related to the theoretical analysis of cement based piezoelectric composite, especially for the 2-2, 0-3 and 1-3 cement based piezoelectric composites. Based on some experimental investigations, the analytical models for the dynamic properties of 2-2 cement based piezoelectric sensors have been established in this paper. Moreover, the exact solutions have been obtained by using the displacement method and comparisons as well as discussions with the experimental results have also been presented and good agreements have been found. It is found that the analytical model established in this paper works very well, which is benefit to the design for this kind of smart devices.
