FAULSense™
The FAULSense™ product line is a hybrid “PZT/FBG” dynamic acousto-ultrasound system that uses a distributed array of piezoelectric “PZT” actuators used as acoustic-ultrasound exciters used to sonicate large structures. These actuators are integrated within a flex-sensor circuit architecture with a distributed array of FBG-sensors receivers that detect and monitor the generated acoustic ultrasound signals which contain structural information of the structure under test. The FAESense™ systems are fully integrated, compact, lightweight, and power efficient available as single-fiber or multi-fiber (2- to 32-fiber channels) data logger transceivers with USB, ethernet, or Wi-Fi data communications modality, to a remote PC software or with on-board data processing and storage.
