Active Wireless System for Structural Health Monitoring Applications

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)...

An Active Sensing Platform for Wireless Structural Health Monitoring

This paper presents SHiMmer, a wireless platform for active sensing that combines localized processing with energy harvesting to provide long-lived structural health monitoring. The life-cycle of the node is extended to 20 years by the use of super-capacitors for energy storage. During this period the node is expected to work completely maintenance-free. The node is capable of harvesting up to ...

A Modular Design for Wireless Structural Health Monitoring Applications

This article presents the research and development activity on the Modular Monitoring System (MMS), a low-power wireless modular architecture for Structural Health Monitoring (SHM) introduced in [1]. The MMS is a device capable to easily interface the vast majority of sensors employed in SHM thanks to a novel modular architecture. In addition, the low-power design allows the MMS to support long...

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...
