Structural Health Monitoring (SHM) is an embedded Non Destructive Testing (NDT) technique that requires the merger of different engineering disciplines such as signal processing, electronics, acoustics, and mechanics. One of the most commonly used detection technique is to emit and receive ultrasonic waves with piezo-electrical transducers attached to the structure. The propagation of the wave is analyzed to evaluate the presence of defects inside the structure. This ultrasonic detection method is particularly appropriate to monitor large structures whose systematic inspections are mandatory but costly, such as aircrafts, spacecrafts, boats,bridges, cables, pipes, etc…

Cedrat Technologies has an extensive experience in the field of piezo-transducers and their related electronics (driving, sensing, controlling), which served as a basis to develop SHM-dedicated electronics solutions. The proposed solutions consist in driving and sensing electronics, ranging from the pure analog rack to the fully programmable solution delivered with Graphical User Interface (GUI).
