The sorters have novel electrode configurations, optimised for high-speed sorting. Increased performance has been achieved by applying plane electrodes instead of line electrodes to increase the dielectrophoretic force. The performance has been further increased by applying a larger number of outlets, to decrease the required particle displacement. Measurements were performed for four different electrode configurations. The best structures achieve more than three times the performance of the classical line electrodes.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"13 1","pages":"64-67 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77689595","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}

Design considerations are made with particular emphasis on the necessities arising from the interplay between sensors, coatings, trap, column, gas fluidics, and pattern recognition software.

Cells are attracted from a liquid suspension by pneumatic anchoring through small orifices (3 /spl mu/m) on the chip surface, which allow for applying suction from the backside of the chip. In contrast to other cell handling techniques, pneumatic anchoring is a very mild, physical technique, which allows for permanent cell immobilization in a parallel fashion. In most cases, pressure needs only to be applied during cell placement, as they afterwards adhere to the protein-conditioned surface and remain at their position. The chip is fabricated using silicon-on-insulator (SOI) wafers by using combined front- and backside etching. Pneumatic particle handling has been studied using polymer beads and living cells suspended in physiological buffer solutions.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"25 1","pages":"80-82 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85051937","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}

By extending this principle to a microtransformer with multiple, evenly spaced cores, a measurement system combining features of analog (variable reluctance) and incremental positioning may be devised. For detecting the direction of motion (to know in which direction to count), an incremental length measurement system requires not just one, but two output signals, which have to be offset by 90 degrees. The paper presents a microtransformer based positioning system fulfilling these requirements. It presents the fabrication technology employed and discusses experimental test results.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"47 1","pages":"1399-1402 vol.3"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85199158","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}

One of the objectives in analyzing high-resolution CTD profiles is to identify turbulent regions (patches) within the flow. Due to the instrumental noise of CTD measurements, the previous methods for turbulent patch identification, reported in the literature, are usually unable to identify patches at low-density gradient. Here we proposed a new method that significantly improves patch detection at low-density gradients. The method is based on a wavelet-denoising procedure and a theoretical analysis of the error in data obtained from the CTD sensors. The high percentage of validating patches, obtained in numerical and field tests, indicates that the method is a powerful tool for fluid dynamics characterization, and can be applied in a wide range of environmental monitoring applications.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"14 1","pages":"1468-1471 vol.3"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85888359","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 system, realized in PCB technology, consists of a double axis fluxgate magnetic sensor with its front-end electronic circuitry based on second-harmonic detection. The amorphous magnetic materials Vitrovac 6025X (25 /spl mu/m thick) and Vitrovac 6025Z (20 /spl mu/m thick) were used as a ferromagnetic core for the sensor. Applying a sinusoidal excitation current of 450 mA peak at 10 kHz with the Vitrovac 6025Z, the magnetic sensitivity was about 1.25 mV//spl mu/T, suitable for detecting the Earth's magnetic field (/spl plusmn/60 /spl mu/T), while the linearity error is 1.5% full scale. Using the thicker Vitrovac 6025X, a maximum sensitivity of about 1.68 mV//spl mu/T and a linearity error of about 1.55% full scale in the range of /spl plusmn/60 /spl mu/T were obtained with a larger sinusoidal excitation current of 600 mA peak at 10 kHz.
