题 目：Recent Advances on Guided-ultrasonic-wave-based Structural Health Monitoring
摘 要：
The past two decades have witnessed prosperity in R&D of burgeoning structural health monitoring (SHM). However, SHM techniques, particular those make use of guided waves, are confronted a few of inherent bottlenecks including the restricted information that conventional linear features can convey, the inefficiency in detecting small-scale damage (e.g., fatigue cracks), and dilemma in striking a compromise between “sensing cost” and “sensing effectiveness”. All these have created a vast barrier towards the real-world deployment of the techniques developed in laboratories. Motivated by this, this talk summarizes the efforts dedicated by the research team led by the presenter over the years, with a hope to circumvent these bottlenecks, partially if not completely. In particular, a coated sensor network made of carbon black and PVDF will be introduced, which is able to facilitate in-situ active sensing of ultrasonic elastic waves. Innovatively, the sensor network can be deposited onto structures under inspection. Such a sensing philosophy retrofits conventional sensor network design, by providing a novel, quick and convenient means to configure a sensor network with quasi-dispersed sensing elements, and circumvents the possible drawbacks associated with the use of distributed sensors (e.g., PZT).
