We have taken an attempt to prepare taste sensor material by using functionalized polymer. Polyvinyl alcohol (PVA) and polyacrylic acid (PAA) have been modified to fabricate the sensor material. The research work covers polymer membrane preparation, morphology study, and structural characterization of membrane and study of the taste sensing characteristics. The membrane was prepared by cross-linking polyvinyl alcohol and polyacrylic acid in aqueous-organic medium by using hexadecyltrimethylammonium chloride (HDTC) with proper heat treatment. The cross-linked PVA-PAA was phosphorylated with POCl3. PVA-PAA membranes of suitable thickness were thus prepared with good threshold sensing value and less swelling in water. FTIR spectroscopic analysis, XRD analysis and optical microscopy were done to get an idea about the structure and morphology of the polymer membrane. Sensor device prepared with this membrane has shown distinct response patterns for different taste substances in terms of membrane potential. The sensor characteristics like temporal stability, response stability, response to different taste substances, and reproducibility of sensing performance were studied. Membranes also showed characteristic response patterns for organic acids like acetic acid, citric acid, formic acid, etc., mineral acids like HCl, H2SO4 and HNO3, etc., salt, bitter substance, sweet substance, umami substance and different grades of tea. Sensor device prepared with this membrane has excellent shelf life.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115437328","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}

Pure ZrO2 films were activated with Cr3+ by dipping them into an aqueous solution (0.1 M) of chromium trioxide CrO3 for different interval of time 5, 10, 20, 30 minutes and fired at 550°C for 30 min. The CrO3 is known to be unstable above 197°C and transform into Cr2O3 upon firing above 197°C. The grain of Cr2O3 would disperse around the grains of ZrO2 base material. The films were characterized by XRD, SEM, EDAS, UV techniques. The gas sensing performance of different target gases was tested and the chromium activated films dipped in 10 Min. was observed to be sensitive. And highly selective 1000ppm of NH3 gas at operating temperature 300°C. The elemental composition were discussed and effect of Cr3+ concentration on sensitivity, selectivity, response and recovery time of the sensor in the presence of different gases were studied. Reaction mechanism were discussed with better performance could attributed to an optimum number of surface misfrits in terms of Cr2O3 on the ZrO2 films. It was first time observed that crominated surface modified film have reduction in bandwidth and observed activation energy were reported.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129128174","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 new sensor possesses the best features of both the schemes and overcomes the demerits of reluctance type sensors. It proposes the use of a spiral shaped element which rotates in unison with the target whose angular position is to be sensed. The rotating spiral varies the reluctance in the flux path of a Hall Effect sensor as sensing angle changes. The resulting variation in the Hall sensor output is shown to be linear using finite element analysis. The scheme does not require any complex signal conditioning circuitry. A simple electronic scheme for calibrating the proposed sensor output against changes in various electrical, magnetic and mechanical parameters is also presented. A prototype angle sensor assembly based on the proposed principle has been built and tested. The output obtained from the sensor was found to be linear, as expected, across a wide range with a worst-case error less than 1%. The new sensor will be useful for various scientific and industrial angle sensing applications.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125981014","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}
