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 of approximately 40 degrees. In operation, as a result of the relative rotation between the plates of the sensor, the operating resonance frequency of the system is shifted. This is read out and tracked in the S-11 response of the transceiver antenna from which the rotation angle is determined. The prototype is designed for microwave regime and it is suitable for measuring very small angles (10(-4) similar to 10(-5) rad). Critical figuresof-merit of the sensor including sensitivity, dynamic range, and resolution are assessed via systematic measurements, and the validity of resolution experiment is verified by employing digital image correlation method for 2-D measurements.

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 ...
An Electromagnetic Sensing System Incorporating Multiple Probes and Single Antenna for Wireless Structural Health Monitoring Ozbey, Burak; ALTINTAŞ, AYHAN; DEMİR, Hilmi Volkan; ERTÜRK, VAKUR BEHÇET; Kurç, Özgür (2017-03-24) 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-lif...
A laterally resonating gravimetric sensor with uniform mass sensitivity and high linearity Eroglu, D.; Bayraktar, E.; Külah, Haluk (2011-09-01) In this paper, a laterally resonating gravimetric sensor with high linearity and uniform mass sensitivity is presented for biochemical sensor applications including rare-cell detection. The sensor utilizes symmetrically placed, balanced, folded spring beam structures to ensure lateral motion of the proof mass and limit the displacement difference between the proof mass center and edges. The dynamic mass sensitivity range of the resonator is increased by using the above mentioned properties of the resonators...
A low-power robust humidity sensor in a standard CMOS process Okcan, Burak; Akın, Tayfun (2007-11-01) This paper presents a low-cost thermal-conductivity-based humidity sensor implemented using a 0.6-mu m CMOS process, where suspended p-n junction diodes are used as the humidity-sensitive elements. The measurement method uses the difference between the thermal conductivities of air and water vapor at high temperatures by comparing the output voltages of two hea ted and thermally isolated diodes; one of which is exposed to the environment and has a humidity-dependent thermal conductance, while the other is s...
