An identification opportunity can easily be added to the sensor element to distinguish between different sensor “tags”. The concept is based on the modulation of the frequency domain backscatter signature of a radar target by the measured value. The target itself is realized as a small resonant metamaterial structure which generates an amplitude peak in the radar cross-section at resonance. The modulation is done by a variation of the capacitive element of the resonator by the measured quantity. Benefits of the presented design are the passive chipless buildup allowing a construction for the operation in harsh (e. g. high temperature) environments, the simple standard, low-cost fabrication process, the small footprint, the identification opportunity, the possibility of a FMCW-radar-based readout and the versatility of possible sensor designs.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128060156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This solution is based on a particular oscillating circuit architecture which performs a “compression” of the higher part of the resistive range, thus limiting the measuring time. The interface is simply implemented by Operational Amplifiers (OAs) and passive components and is suitable to be integrated in a single chip. Since it employs an AC excitation voltage for the sensor, this front-end results to be capable to estimate both the sensor resistance over a wide range (5 decades) and its in-parallel parasitic capacitance, for diagnosis purposes and complete characterization of the sensor. PSpice simulation results have shown the feasibility of the proposed approach; in addition, experimental measurements, conducted through the fabricated prototype PCB and utilizing commercial sample resistors and capacitors to emulate sensor behaviour, have shown good performance in the resistive range 100kΩ–10GΩ with a maximum measuring time set to about 70ms, so confirming the theoretical expectations and the validity of the proposed sensor interface.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131375138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SCF employs a periodic heating technique rather than continuous heating and calibrates itself every 5 seconds. This approach ensures zero drift for long-term continuous monitoring and can provide reliable data with MEMS-based thin film sensors. In addition, it uses a 4-wire configuration to eliminate lead wire effect and employs ratiometric measurement to deduce the resistance of SCF. Hence, it is more precise when compared to the bridge-type thermal diffusion flow sensor. The developed SCF has a sensitivity of 2.47mV/ml/min in the range from 0 to 100ml/min with a linear correlation coefficient of R2 = 0.9969. It achieves a resolution of 0.5ml/min and an accuracy better than 3ml/min of full scale with both temperature and medium thermal conductivity compensation.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131983385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor is based on Faraday rotation and on the analysis of the state of polarization of the Rayleigh backscattered field. Specifically, the sensor measures the projection of the magnetic field vector in the direction of the fiber. By exploiting this feature and properly arranging the fiber, multi-dimensional maps of the magnetic field can be built. Owing to the faintness of Faraday rotation in standard optical fibers, the proposed sensor is most suited for intense magnetic fields. Experimental results are presented to show the successful measurement of the magnetic field of a 1.5-T magnetic resonance imaging scanner, with a relative accuracy of about 7% and a spatial resolution (along the fiber) of 3 cm.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132415710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
