This Small Business Innovation Research Phase II project is to fabricate, characterize, and verify performance of a new type of frequency steered acoustic transducer (FSAT) for structural health monitoring for impacts and leaks in aerospace structures. FSATs will be demonstrated both in the laboratory and on relevant NASA structure. Testing would be performed on both simple and complex parts. Multiple receivers would be tested to develop incoming signal analysis, angular distribution mapping, and source detection and localization. In addition, Genziko will evaluate the suitability of its integration into a wireless system, using a micro power generator and RF transceiver.
