The three-electrode sensors were designed as disposable ones and for monitoring. Disposable sensors were made by the screen-printing of the electrode material on polymeric foils, the other ones were made by screen-printing on ceramic or by platinum evaporation onto silicon wafer. Potential applications of the developed amperometric sensors for enzymatic, enzyme-cofactor mediated assays and phenothiazine-based drug detection were demonstrated. It was stated that, the PPy layer deposition on Pt electrode might lead to use of this material to decrease an oxidation potential of NADH in the NAD regeneration process.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116600444","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 Transmission Electron Microscope studies showed that at annealing temperatures below 600 K the films consist of fcc Cu and hcp Co. After annealing at higher temperatures, besides the presence of phases already observed at lower temperatures, also Co-Cu solid solution together with single phase of hcp Co was observed.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"6348 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129592852","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}

However, available literature about passive multiband systems concentrated exclusively on problem of temperature measurements with these systems in situation when these systems can be also used for non-contact emissivity measurements. Modeling of such systems, what is usually the first stage of system designing, requires acceptation of several simplifications and approximations. In this paper an experimental verification of modeling results is performed based on developed measurement setup. Obtained results are in good agreement with results of previously performed computer analyses that shows usefulness of multiband method for emissivity measurements in working conditions.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126344652","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}

Its working principle is based on electric current acquisition, while voltage ramp is applied to the sensor. The current-voltage plot has unique shape, which depends on surrounding gas type and its concentration. Response of the electrocatalytic gas sensor contains significantly more information in comparison with typical amperometric or potentiometric one. Methods of sensors response analysis, which was employed so far, did not fully utilize this feature. Moreover, shape of sensor response, in case of some gases or mixtures, is hard to be interpreted with traditional techniques. In this work more advanced methods to analyze electrocatalytic gas sensor response, which are based on explorative and confirmative techniques as well as artificial neural network, are presented.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126596897","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}
