| Abstract: |
| Attention was focused on the study of the feasibility of the cement based piezoelectric smart composites, including problems in fabrication, polarization and adjustability of acoustic impedance of the composites. The results show that using cement based materials as matrix of piezoelectric smart composites can solve the mismatch problem, fabrication problem, and reduce the polarization voltage. This results in high polarization efficiency, good piezoelectric properties and low price. |
