In this study, a wireless and passive displacement/strain sensing system is proposed for structural health monitoring (SHM). The wireless and passive interrogation of the sensing unit [a variant of a nested split-ring resonator (NSRR)] is achieved through the near-field interaction and electromagnetic coupling between the single antenna in the system and the multiple sensors called the NSRR probes. It is demonstrated that the system can acquire data from more than one NSRR probe simultaneously in a real-life scenario, where the probes are confined within concrete inside a beam, while the antenna monitors them from outside.

A Wireless Passive Sensing System for Displacement/Strain Measurement in Reinforced Concrete Members
Ozbey, Burak; ERTÜRK, VAKUR BEHÇET; DEMİR, Hilmi Volkan; ALTINTAŞ, AYHAN; Kurç, Özgür (2016-04-01)
In this study, we show a wireless passive sensing system embedded in a reinforced concrete member successfully being employed for the measurement of relative displacement and strain in a simply supported beam experiment. The system utilizes electromagnetic coupling between the transceiver antenna located outside the beam, and the sensing probes placed on the reinforcing bar (rebar) surface inside the beam. The probes were designed in the form of a nested split-ring resonator, a metamaterial-based structure ...
A Wireless Metamaterial-Inspired Passive Rotation Sensor With Submilliradian Resolution
Gargari, Ali Maleki; Ozbey, Burak; DEMİR, Hilmi Volkan; ALTINTAŞ, AYHAN; Albostan, Utku; Kurç, Özgür; ERTÜRK, VAKUR BEHÇET (2018-06-01)
A novel passive wireless rotation sensing system with high levels of sensitivity and resolution is proposed and demonstrated for measuring elastic-region bending in materials such as steel. This system is composed of a transceiver antenna and a double-plate sensor in the form of an inter-digital configuration, which does not incorporate any active component. The sensor exhibits a large rotation resolution of 20 mu-rad, an excellent sensitivity of 28 MHz/degrees in average, and a large linear dynamic range o...
A smart couch design for improving the quality of life of the patients with cognitive diseases Bi̇li̇şsel rahatsizliklari olan ki̇şi̇ leri̇n yaşam kali̇tesi̇ni̇ artirmak i̇çi̇n akilli bi̇r koltuk tasarimi
Ertan, Halil; Alemdar, Hande; Incel, Özlem Durmaz; Ersoy, Cem (2012-07-09)
In this paper, we focus on the human activity recognition module of a homecare system that consists of wireless sensors developed for remotely monitoring patients with cognitive disorders, such as Alzheimer. To this end, as an initial study, we designed a smart couch that is equipped with accelerometer, vibration and force resistive sensors to monitor how much time people spend while sitting, lying or napping on the couch and to recognize the drifts from their daily routines. In order to distinguish these a...
Design of a Novel THz Sensor for Structural Health Monitoring Applications
Pavia, J. P.; Ribeiro, M. A.; Sarikaya, C. K.; Akbar, D.; Altan, Hakan; Souto, N. (2019-01-01)
In this paper, we propose a study on the characterization, design and simulation of a THz sensor for applications in Structural Health Monitoring (SHM). The proposed sensor is assembled using two frequency selective surfaces (FSSs) based on metamaterial wire resonators. We present a theoretical model to describe its electromagnetics which is used not only to understand the physical principles underlying the functioning of the sensor but also to determine a set of optimized parameters for its operation in th...
Multi-Point Single-Antenna Sensing Enabled by Wireless Nested Split-Ring Resonator Sensors
Ozbey, Burak; ERTÜRK, VAKUR BEHÇET; Kurç, Özgür; ALTINTAŞ, AYHAN; DEMİR, Hilmi Volkan (2016-11-01)
In this paper, simultaneous multi-point wireless sensing is proposed and demonstrated via multiple sensors in nested split-ring resonator (NSRR) geometry coupled to a single illuminator antenna. In this passive multi-point sensing system, each probe in the sensor array is assigned a non-overlapping spectral interval for frequency shift in response to local mechanical loading around a unique operating resonance frequency in the band of the antenna. Here, it is shown that the antenna is capable of capturing t...
