The films are deposited on a glass epoxy substrate having copper electrodes in interdigited form. They are deposited at different RF powers in the range from 10 to 45W keeping other plasma parameters fixed. Thickness is found to be varying between 150-250nm. Chemical structure of polymer is studied using FTIR technique. Basic response of the polymer to relative humidity in the range 0 to 92% is measured, in terms of capacitance variation for films deposited at different powers. The sensitivity, measured as change in capacitance with change in humidity, is found to be different in different humidity ranges. Sensitivity is low in lower region of humidity range and larger in higher range of humidity. For response and recovery time of the film, the change in resistance over time is recorded after every 30 s till the resistance showed saturation. They are found to be 118s and 63s respectively. The results are analyzed and compared with those available in the literature.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84042218","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 film of PMMA, when tested for relative humidity sensing using direct optical transmission gives response in the range 80–92% RH. To increase the range of response, PVA, higher hydrophilic, was spin coated on PMMA, layer by layer. It was found that with the 4th layer of PVA over PMMA, wide sensing range (2–92%RH) is covered, with three distinct regions of sensitivity. To achieve linearity over the complete relative humidity sensing range, Ag particles were added in PVA, and coated on PMMA. This resulted in linear response (1.85 mv/%RH), over a wide range of RH (2–95%). The concentration of Ag, having 5∶2 by volume of PVA and Ag gives good linearity (R2 > 0.99) with response and recovery time of 15 and 18 sec respectively with 4% hysteresis and good repeatability.(tested over 7cycles.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87499154","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 efficiency of nano-scale platinum catalysts at the fuel cell cathode is highly susceptible to carbon monoxide (CO) poisoning and results in irreversible damage to the electrode. Higher CO2 level in air does not induce catalytic poisoning, however it lowers the partial pressure of O2 at cathode. This results in a drop of fuel cell output power. Our work proposes a combined range sensing and proximate sensing based approach for tracking of smoke plume. Our approach helps to tackle the PEMFC degradation issue by forecasting nature of the plume in vicinity of the fuel cell. The simulation results quantify the dynamic changes in PEMFC electrode resistance with respect to higher levels of CO concentration in air. Drop in fuel cell output power with respect to higher mass fractions of CO2 and ambient humidity are also quantified in this work. The proposed threat prediction based approach helps to enhance the lifetime of a field deployed air PEMFC by reducing and/or inhibiting the air contaminant based fuel cell degradation mechanisms.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86328055","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}
