Development of a Wireless Displacement Measurement System Using Acceleration Responses

Displacement measurements are useful information for various engineering applications such as structural health monitoring (SHM), earthquake engineering and system identification. Most existing displacement measurement methods are costly, labor-intensive, and have difficulties particularly when applying to full-scale civil structures because the methods require stationary reference points. Indi...

Wireless Monitoring Techniques for Structural Health Monitoring

Recently, a variety of wireless structural health monitoring systems have been demonstrated as viable substitutes for traditional high-cost tethered monitoring systems. In this study, a prototype wireless sensing system is deployed on the Voigt Bridge (La Jolla, CA) and a historical theatre (Detroit, MI) to validate its performance against cabled monitoring systems. Acceleration time history re...

Active Wireless System for Structural Health Monitoring Applications

The use of wireless sensors in Structural Health Monitoring (SHM) has increased significantly in the last years. Piezoelectric-based lead zirconium titanate (PZT) sensors have been on the rise in SHM due to their superior sensing abilities. They are applicable in different technologies such as electromechanical impedance (EMI)-based SHM. This work develops a flexible wireless smart sensor (WSS)...

Embedding Actuation Functionalities in a Wireless Structural Health Monitoring System

Structural health monitoring is a broad field that encompasses a number of synergetic technologies that together can provide a system to identify and characterize possible damage present within a structure. Such a system should include data acquisition subsystems capable of recording a structure’s response to ambient and external loads. Furthermore, it is now possible to include computational h...
