Electrical Response of Cement-Based Piezoelectric Ceramic Composites under Mechanical Loadings

Abstract EN

Electrical responses of cement-based piezoelectric ceramic composites under mechanical loadings are studied.

A simple high order model is presented to explain the nonlinear phenomena, which is found in the electrical response of the composites under large mechanical loadings.

For general situation, this nonlinear piezoelectric effect is quite small, and the composite is suitable for dynamic mechanical sensor as holding high static stability.

The experimental results are consistent with the relationship quite well.

The study shows that cement-based piezoelectric composite is suitable for potential application as dynamic mechanical sensor with excellent dynamic response and high static stability.
