监测复杂工程结构的状况是现代工程的一个重要方面，消除不必要的工作，实现计划性维护，防止故障。声发射检测是实现结构健康连续无损监测的一种方法。提出了一种新型厚膜（17.6 μm）声发射传感器。采用粉末/溶胶复合油墨沉积技术制备了锆钛酸铅厚膜，并对其进行机械图案化以形成分立的厚膜压电声发射传感器。厚膜传感器的基准对商业AE设备，并被发现表现出相当的响应模拟声发射。
Monitoring the condition of complex engineering structures is an important aspect of modern engineering, eliminating unnecessary work and enabling planned maintenance, preventing failure. Acoustic emissions (AE) testing is one method of implementing continuous nondestructive structural health monitoring. A novel thick-film (17.6 μm) AE sensor is presented. Lead zirconate titanate thick films were fabricated using a powder/sol composite ink deposition technique and mechanically patterned to form a discrete thick-film piezoelectric AE sensor. The thick-film sensor was benchmarked against a commercial AE device and was found to exhibit comparable responses to simulated acoustic emissions.
