A time reversal focusing based impact imaging method and its evaluation on complex composite structures
TL;DR: In this paper, a time reversal focusing based impact imaging method for impact localization of complex composite structures is proposed, where a complex Shannon wavelet transform is adopted to extract frequency narrow-band signals of impact response signals of a PZT sensors array at a special time-frequency scale and to measure the phase velocity of the signals.

A stretchable and large-scale guided wave sensor network for aircraft smart skin of structural health monitoring:
TL;DR: A design and manufacturing method of a stretchable and large-scale guided wave sensor network that can be applied to both active and passive guided wave–based structural health monitoring of composite structures, including damage imaging and impact imaging is proposed.

A piezoelectric sensor network with shared signal transmission wires for structural health monitoring of aircraft smart skin
TL;DR: Experimental results show that the PZT Layer can accurately detect structural impact and damage regions based on the SHM methods, demonstrating that the proposed PzT sensor network with shared signal transmission wires can significantly reduce the number of wires and monitoring channels and has great potential in aircraft smart skin applications for both passive and active SHM.
