Comparing to other calibration methods, such as the use of MFM (Magnetic Force Microscope), sealed fluidic flow cells, current lines, etc., the proposed SPEM method has four major advantages: no magnetic background, a precisely controlled number of particles which is mostly single-layered, pristine GMR surface after calibration, and mass fabrication. The SPEM is made from a superparamagnetic particle embedded SU-8 post and a glass cantilever. It can calibrate the magnitude of GMR signals to the number of superparamagnetic particles by bringing a known number of single-layered particles close to the GMR surface while still keeping the GMR surface pristine for future biofunction.","PeriodicalId":185824,"journal":{"name":"2005 International Conference on MEMS,NANO and Smart Systems","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132291795","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}

For the past few years, this technology has witnessed significant development but continues to be limited to trial studies on legacy aircraft. To exploit the full benefits of this promising technology in developing an integrated airframe condition-based maintenance system, several challenges need to be addressed. A major one is the development of lightweight, small size, reliable, robust handheld multisensor interrogation system. This paper highlights our current fiber optic sensor capability; identifies current implementation challenges on aerospace platforms and presents a proposed state of the art alternative. This alternative uses an arrayed waveguide gratings (AWG) based demultiplexer and provides a system resolution of 0.1/spl deg/C and 1/spl mu//spl epsiv/ for temperature and strain monitoring, respectively, in addition to the added benefits of weight and size.","PeriodicalId":185824,"journal":{"name":"2005 International Conference on MEMS,NANO and Smart Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115724696","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}

But the bends or curves degrade the performance of separation efficiency. To tackle this problem, channels are modeled with different types of 90 degree turns to reduce the \"racetrack\" effect. In this paper, the finite element method is used to numerically solve the equations governing electroosmotic flow and mass transport in a microchannel. The detailed results show that the sample plug broadening due to turns can be reduced when the outside of the turn is dented. It is also suggested that the band tilting can be corrected.","PeriodicalId":185824,"journal":{"name":"2005 International Conference on MEMS,NANO and Smart Systems","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117163198","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}

Over the past decade BioMEMS implants have been used as neural interfaces for promoting axon growth. This article reviews the usage of BioMEMS implants as electrical stimulation neural interface and as hybrid ones. Animal experiments of these neural interfaces have presented important results that hopefully the treatment for injured spinal cord will be developed in the near future.","PeriodicalId":185824,"journal":{"name":"2005 International Conference on MEMS,NANO and Smart Systems","volume":" 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113948221","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}

This work is to study the effect of gravity on the advancing contact angle for a sessile drop. Purified water (millipore direct-Q) has been used as the liquid in this experiment. Teflon-coated silicon wafers were used as solid substrates. Images of the advancing drop were taken during the reduced gravity period. The advancing rates of the three-phase contact line were 6.5-9.0 mm/min. The high linear regression coefficient indicated that the advancing rate of the three-phase contact line can be considered almost constant for a particular pumping speed. Similar experiments were also performed on ground for comparison. The contact angles for the reduced gravity images were calculated by two different methods. The first method is axisymmetric drop shape analysis-profile (ADSA-P). The second method, geometrical relations for a spherical cap were used to calculate the contact angle from the images of the drop. The results were good agreement indicating that gravitational effects were negligible compared to surface effects. The average of the advancing contact angle in reduced gravity was 121/spl deg/. The average of ground-based contact angles was 126/spl deg/. The results show that, for water sessile drops on Teflon-coated silicon wafers, the advancing contact angle in the reduced gravity environment is less than the advancing contact angle in 1-g by about 5/spl deg/. The irreproducibility of the contact angle might be due to airplane vibration.","PeriodicalId":185824,"journal":{"name":"2005 International Conference on MEMS,NANO and Smart Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125341169","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}
