It consists of an N-well/P-substrate diode without salicide and 2D metal-grating layers on the diode. The periods of the 2D metal structure are controlled to realize color filtering. We implemented sixteen kinds of the pixels with the different metal-grating structures in a standard 0.18µm CMOS process. The measured results demonstrate that the N-well/P-substrate diode without salicide and with the 2D metal-grating structures can serve as the high speed RGB color active pixel sensor for real-time vision chips well.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132677175","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}

Being embedded, the PZT ceramic is in a complicate environment which results in the changes of physical properties of PZT element. In this paper, a new method of measuring energy losses is first proposed to evaluate the effect of such physical changes. In order to measure the energy losses, the corresponding dissipation factors are calculated from the piezoelectric equivalent parameters. In the stress and temperature experiments, two kinds of PZT ceramic perform different features which also result in changes of energy losses. It is also found that when the environment temperature is unstable, the changes of the equivalent parameters are in fact the results of both the effects of stress and temperature. However, comparing the stress with temperature experimental results, it is found that the eigen frequencies of the embedded piezoelectric ceramic perform special characteristics that they are more sensitive to temperature than to stress. It enables us to solve the problem of the stress and temperature cross sensitivity.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126581872","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}

Monitoring the temperature of an LPG tank is one of the safety measures in the operation of tank-lorry carrying the LPG. Surface temperature of LPG tank should be maintained below predefined value which is 40°C for example. Temperatures at several regions in the tank were monitored by temperature sensors modules which are attached on the surface. To get temperature field in a given region, we proposed a technique of using radial basis neural networks. The proposed method is simple and directly performed with less computational complexity than conventional physical model based approaches. The experimental results were well performed in the estimation of a spatial temperature distribution.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134475768","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 bio-sniffer is a gas sensor that uses molecular recognition of enzyme to improve selectivity. Usually, enzyme loses activity in the gas phase. Applying a flow-cell with a gas-intake window to the sensing probe, enzyme immobilized at the sensing region was kept in the sufficient wet condition to maintain activity. The bio-sniffer measures ethanol (EtOH) vapor by measuring fluorescence of nicotinamide adenine dinucleotide (NADH), which is produced by enzymatic reaction at the flow-cell. In order to construct a simplified system suitable for on-site applications, a high-intensity ultraviolet light emitting diode (UV-LED) was utilized as an excitation light. Owing to low power consumption comparing with previous light sources, the bio-sniffer was considered to be suitable for laptop applications such as on-site monitoring. According to the characterization, the bio-sniffer for was useful for continuous alcohol monitoring and showed high selectivity. The calibration range was 0.30–300 ppm which is suitable for evaluation of capacity to metabolize alcohol.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133808093","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}

It consists in detecting and locating electric faults in wiring networks while the target system is running. Since the system is diagnosed on line, it is necessary to minimize interferences between the target system and the reflectometer. The Multicarrier Time Domain Reflectometry presented here allows a complete control of the spectrum of the injected signal in order to adapt it to the application constraints. The measurement error due to the spectrum distortion and a post-processing is proposed to provide valid reflectometry result close to those of classical methods for complex networks.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115719823","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 MoOx gas sensing layers have been achieved with varying carbon concentration. Structural and morphological characterization by means of SEM TEM and XRD indicate that carbon is incorporated into MoOx nanoneeles but carbon doping does not considerably affect surface morphology and crystal quality. Electrical characterizations highlight interesting behaviors for the layer tested. The MoOx film's conductance decreases by more than one order of magnitude with carbon doping. As carbon content increases, acetone and particularly ethanol responses are significantly improved by more than an order of magnitude. In contrary, hydrogen and methane response are low and relatively insensitive to carbon content. Therefore, carbon doping makes MoOx nanoneedles more selective toward volatile organic compounds (VOCs) than hydrocarbon gases.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114788148","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}
