In this paper we present a wireless embedded system that performs active ultrasonic Structural Health Monitoring (SHM). The proposed Shimmer platform is an autonomous, battery-less system, powered by an energy harvester, which uses 16 piezoelectric sensors/actuators attached to the structure surface for SHM analysis. The collected data (≈4MB) are analyzed by the on-board DSP and the result...
Wireless Sensor Network is an emerging technology which can significantly reduce the cost and the time needed to monitor the conditions of civil structures. This work presents W-TREMORS, a new wireless sensing system for high-frequency distributed data acquisition. Our sensor network is based on the low-power and low-data rate standard IEEE 802.15.4, and we used inexpensive hardware. Nevertheless,...
Structural Health Monitoring (SHM) systems have been used with many important structures to enhance the public safety and to reduce the economical losses. Wireless Sensor Networks (WSN) is an emerging technology which can be deployed with SHM applications. However, some system requirements have been overlooked in the current WSN designs for SHM applications. Therefore a complete analysis in system...
Recent proliferation of sensor networks in diverse applications has made the low-power wireless sensor network an important design issue. Structural health monitoring is one of the important applications of the wireless sensor network. A robust wireless structural monitoring strategy requires appropriate choice of the wireless network topology as well as some suitable protocols. This paper presents...
