SUMMARYA wireless and battery-free passive sensing platform is proposed for structural damage detection. The platform is based on the radio-frequency identification (RFID) technology, where a standard RFID transponder device serves as an interface between low-power sensors -used for damage detection -and RFID reading devices. Sensor data are transmitted remotely from this sensing platform to a Personal Computer (PC) that controls the entire system. Energy harvesting is the major novelty of the proposed approach. The magnetic field produced by an antenna of the RFID reading device is used for energy harvesting. The platform supports different types of sensors that can be positioned in remote locations and used for structural damage detection. The sensing capability and the damage detection performance of the proposed system are demonstrated using two simple application examples, that is, vibration measurements in a beam-like structure subjected to the force excitation and temperature measurements in a bearing that supports a rotating shaft. The results illustrate the great potential of the proposed sensing platform for structural health monitoring applications, particularly in remote, difficult-access, or hazardous conditions.

“…They all are wired connected to a central acquisition system located in the building itself. Accelerometers, gages, fibre-optic strain sensors, laser based displacement sensors, and acoustic emission sensors and so on, have also been used to measure the changing characteristics of a building under retrofitting, as the construction progressed (Chassiakos et al, 2007). Very widespread is also remote monitoring of bridge structures (Mehrani et al, 2009), as their deterioration must be estimated and life time expectancy predicted, in order to assure user safety, which is critical also in many other public civil works (Bhalla et al, 2005).…”

The constant innovation in the development of sensing devices for detecting health status of buildings, highlights the importance of this professional field. In fact, correct diagnosis would prevent many pathologies, driving maintenance interventions towards timely and well targeted operations. This paper describes the development of a monitoring system prototype, conceived to be very low intrusive, that can be applied also on existing buildings, without any need to predispose chases for power or communication cables. Its adoption is expected to be useful not only for standard health status monitoring of buildings during their lifecycle, but also for automated monitoring of old buildings during the conduction of works for their renovation. As a matter of fact in this case accidents due to unexpected collapses during work execution are very common, hence the static condition of buildings should be continuously checked automatically and alerts sent in case of high risk of failures. The sensors under development have been programmed in such a way to be able to monitor rotations and send alerts in case critical thresholds are overcome.

“…Traditional monitoring systems for vibration data collection from civil structures are based on networks of wired or wireless accelerometers and strain gages distributed along the structure . A major inconvenience of traditional sensor arrays is the cost of the sensors and electrical cables, as well as the significant labor in installation.…”

Summary A new methodology for the monitoring of dynamic characteristics of buildings has been proposed. It is based on digital image analysis leveraging pre‐existing cameras installed within a building, such as surveillance cameras. The method is used for real‐time measurement of interstory drifts, from which dynamic characteristics (e.g., fundamental period) can easily be extracted to detect damage to the structural system. It has applications particularly in the case of post‐earthquake damage estimation and when the installation of traditional sensors and monitoring systems is cost prohibitive. The methodology is demonstrated through both lab‐scale and full‐scale shake table tests.
