Abstract:In this work, we report on some research developments to support the upscaling of nondestructive evaluation and structural health monitoring (SHM) approaches, mainly based on ultrasonic guided waves, for aeronautical applications. In particular, first a spiral-shaped piezoelectric sensor sensitive to the wave direction of arrival (WDA) of guided waves propagating in plate-like structures is described. Next, a miniaturized sensor node capable to perform locally signal processing algorithms, as those developed f… Show more
