It is possible to actively and continuously detect the dynamic characteristics of the structure in a long term by embedding piezoelectric devices into concrete structures without any power supply.To fulfill the detection of static performances by the same sensing network,some (or a) devices are used as acoustic sources excited by alternating electric signal to generate acoustic vibration within the structure.The acoustic wave propagates in the structure and both the dynamic and static properties of the structure will modulate the wave.The rest of the piezoelectric devices still function as sensors to pick up the acoustic wave and convert it into electric signal.This paper introduces the technology of smart concrete based on piezoelectricity and its realization.
