Research and Application of Integrated Health Monitoring Scanning System Based on PZT Sensor Array

Structural health monitoring can enhance the function,safety,reliability of structures,reduce the maintenance cost,and increase the life-cycle.Structural health monitoring using PZT elements and Lamb wave active diagnostic approach is a typical,useful and popular method.Recently,most routine structural health monitoring systems are mainly used in laboratory,which are realized by lots of independent instruments.Many of these system are complicated,weighty,having much wire,and inconvenient to be used in engineering applications.A kind of integrated multiple PZT channels scanning system was proposed and produced in this paper.The function of this integrated system had been proved in an application.
