Corrosion induced material loss in metallic structures is a widespread and urgent problem
across multiple industries. In this paper, a novel corrosion monitoring method is proposed …

The traditional monitoring methods can only give warnings for the bolts with severe
looseness. However, it is essential for the safety of bolted joints to detect the looseness of …

In this paper, a novel but practical approach named series/parallel multi-sensing technique
was proposed to evaluate the bolt looseness in a bolt group. The smart washers (SWs) …

An application for sensing the stress-induced localization of damage in the form of a discrete
crack in a concrete substrate is developed using embedded PZT patches. Stress-wave …

Traditional manufacturing approaches to embed active materials, such as piezoelectrics,
into metals can be problematic due to their high process temperatures or long curing times …

A simply strategy for monitoring the corrosion process via the peak-to-peak amplitude of
ultrasonic guided waves is performed to capture the initial and cover cracking stage of …

An algorithm to detect damage size and shape using a lead zirconate titanate (PZT)
transducer array for a plate structure is developed in this paper. During the process of …

Stress wave-based communication has great potential for succeeding in subsea
environments where many conventional methods would otherwise face excessive difficulty …

A novel embedded piezoelectric ultrasonic transducers suitable for damage monitoring of
steel bar were developed, and the crack and corrosion damages of the steel bar were …

This paper deals with lifelong monitoring of concrete structures using embedded
piezoelectric transducers. Thanks to such transducers, monitoring of the concrete can be …
