TL;DR: In this article, an automated phase correction (APC) algorithm is proposed to properly trace and compensate phase angles of the complex logarithmic function which may experience abrupt phase jumps near the resonant frequency region of the concerned EMMs, and hence the continuity of the effective optical properties of lossy metamaterials is ensured.

TL;DR: In this article, a method for direct measurement of Mode-I stress intensify factor of cracks using Ba0.64Sr0.36TiO3 flexoelectric sensors was presented.

TL;DR: In this paper, the authors explore the relationship between the sensor signal amplitude and crack size through experiments and simulation for estimating the size of a crack in an aluminum plate and measurements are carried out with ultrasound excitation using piezoelectric transducer arrays that alternate their role as actuators or sensors.

TL;DR: A real-time, in-process cure monitoring system employing a guided wave-based concept for carbon fiber reinforced polymer composites was developed and demonstrated the capability of using an embedded phase-shifted fiber Bragg grating to sense a wide bandwidth of signals during cure.

TL;DR: In this article, the Viscoelastic (VE) dampers, as a common shock absorber, are used to detect damage to high-rise buildings, which is essential to be able to detect damages to them.
