摘要

结构健康监测(SHM)系统允许永久和在线表征结构部件的状态和健康。我们介绍了完全基于无机材料的新型SHM模块,与已知的压电陶瓷聚合物贴片相比,该模块在温度和化学稳定性方面有显著改善。采用陶瓷多层技术,将锆钛酸铅(PZT)圆盘集成到低温共烧陶瓷(LTCC)片的封装中,从而可以生产具有集成电子电路和信号处理单元的紧凑超声波换能器。

Robust structural health monitoring transducers based on LTCC/PZT multilayer
Structural Health Monitoring (SHM) systems allow for permanent and online characterization of condition and health of structural components. We introduce novel SHM modules fully based on inorganic materials which show a distinguished improve of temperature and chemical stability compared to known piezoceramic-polymer-patches. Using ceramic multilayer technology lead zirconate titanate (PZT) discs are integrated into a package of low temperature cofired ceramic (LTCC) sheets enabling for the production of compact ultrasonic transducers with integrated electronic circuits and signal processing units.
