The sensor is fabricated using thick film technology. The intention was to prepare a base substrate for study of properties of materials used for working electrodes fabrication. In this work, the main emphasis was on sensor design and on materials of working and reference electrodes to ensure reproducible and reliable detection of heavy metals with sufficient limit of detection. In this work, various graphite materials for sensors working electrodes were prepared, screen-printed, measured and compared with a classical graphite electrode.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"58 1","pages":"749-752 vol.2"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75433256","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}

A novel methodology of application of a torque to the magnetoelastic sensing elements is described. In this solution, uniform torque is applied by special, nonmagnetic backings with radial grooves. These backings are glued to the core. The developed method was applied for the measurement of the influence of torque on magnetic properties of Fe-based, metallic glass (Fe/sub 78/Si/sub 13/B/sub 9/) in as-quenched and annealed state. Results presented in the paper confirm that this method can be utilized in construction of the new class of magnetoelastic torque sensors.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"96 1","pages":"505-507 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75863323","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}

Depending on the evaluation algorithm, two different shapes are commonly used; these rotors produce trapezoid or sinusoidal capacitance patterns. However, capacitance patterns which allow the construction of more accurate and more robust estimators of the desired parameter can be used. In general, position estimation is a nonlinear process, therefore the most accurate estimator is computationally expensive. In this paper an approach for robust optimal design of sensors with suboptimal estimators is presented. The optimal design is obtained by a tight coupling of statistical and field numerical methods taking into account uncertainties arising from inaccuracies of the topology, electronic component tolerances and measurement noise. It is shown that all these factors have substantial impact on the optimal shape of the rotor.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"1 1","pages":"520-523 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75580789","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 ATR element has been incorporated in a flow cell connected to the fermentation process under investigation via a flexible computer controlled flow system for online monitoring. Measurement of dissolved components is achieved while pumping the sampled fermentation broth through the flow cell. Upon stopping the flow, the microorganisms can be monitored subsequently as they settle on top of the horizontal ATR element. Because of the surface sensitivity of ATR spectroscopy, the cleanness of the ATR surface must be guaranteed throughout a prolonged operating time. For certain bioprocesses, the formation of bio-films on the ATR surface was identified as an important difficulty as they cannot be removed by simple rinsing with distilled water or simple washing solutions such as NaHCO/sub 3/. Therefore, different chemical solutions have been tested for efficient bio-film removal. Among the studied solutions, the use of oxidizing agents (e.g. H/sub 2/O/sub 2/) in concentrations around 2% proved most effective.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"3 1","pages":"742-745 vol.2"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74345562","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}
