This material has a lower refractive index compared to the refractive index of the optical fiber. This characteristic limits the sensitivity of the sensor. In order to enhance the sensitivity to humidity it has been intercalated a high refractive index layer, which permits to improve the sensitivity of LPFG sensors by a ratio of four. The method proposed here widens the design of LPFG based sensors characterized by overlays of low refractive index, and could be used for other applications such as the design of optical filters.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131733521","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 best sensitivity and linearity of the sensor were obtained for the pulses with the highest DC component.

The key point is the lamination factor which refers to the ratio of winding number compared with an ideal Brooks-coil. A decrease in lamination factor produces an increase in flux-to-voltage transfer ratio, and a decrease in noise floor level of the magnetometer. The size of coil defines the 20 dB/decade slope in frequency response of the magnetometer. While a magnetometer consisting of a coil with low lamination factor has high cutoff frequency, the sensitivity is better than of a coil with high lamination factor even if the frequency is lower than the cutoff frequency. Some magnetometers having few hundred ft/Hz1/2 are fabricated, and demonstrate the validity of the idea. This design method may allow us to develop an ultra-sensitive, high-spatial-resolution induction magnetometer comparable to SQUID sensor.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125730808","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 length/width aspect ratios of the membranes range from 5 to 22. For each design, multiple samples were fabricated in order to collect statistically meaningful data. The performance of pMUTs was characterized by the impedance and phase angle measurements combined with equivalent circuit analysis. The circuit has four electrical components, L1 (motional inductance), C1 (motional capacitance), R1 (motional resistance), and C0 (parallel capacitance), and their values were determined by fitting the circuit equation to the experimental data. The experimental results showed that effective coupling coefficient ( keff 2) increase, and resonance frequency ( fs) and quality factor (Q ) decrease with increasing the width of the membrane.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121214521","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}
