Lightweight and conformal acousto‐ultrasonic sensing network for multi‐scale structural health monitoring: A review

open access: yesFlexMat, EarlyView.
This systematic review mainly covers a collection of acousto‐ultrasonic sensors, two modalities of network installation, and their employment with multi‐scale monitoring methods. The weight increase and conformability of different sensing networks are discussed, as the two major challenges for developing structural health monitoring systems of complex ...
