The long-test stability of the investigated samples was researched. It is shown that additives silver and yttrium in the presence of Pt/Pd on the surface provide the maximum values of the response to hydrogen at 670 K. In the cases of the depositec catalytic silver the response to hydrogen is considerably lower. II according with the results of the experiments, the characteristics of the films with additions of silver+yttrium in the bulk have weaker dependence on humidity changes. A common feature of samples with modifiers of silver and yttrium is the high stability of their properties under the periodical influence of hydrogen in long-term tests. Analysis of results shown that the complei modifiers of silver+yttrium interact with lattice atoms of tin and oxygen contribute to the emergence of deep centers in the semiconductor, and these additives prevent the process o reduction of tin dioxide at hydrogen adsorption and ensure the stability of the parameters of the sensors in operation.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120976211","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}

In the present study, a very simple and straightforward micro-pattering approach based on well known dry etching has been presented. The dry etching of silk microstructures was achieved using low pressure oxygen plasma ashing technique. Titanium based stencil mask patterned using photolithography, was used to transfer the desired microstructures onto the silk film. The optimum etching recipe was determined by optimizing the dry etching parameters like RF power delivered onto the carrier, duration of plasma and the oxygen flow rate. The etch rate and the etch uniformity were measured using standard metrological techniques. Selective complete removal of silk with an etch rate of 0.20 urn/min has been reported. Using the optimized dry etching recipe, a complex pattern with minimum feature size of 1.6 µm was achieved.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127334099","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 output neurons of retina, retinal ganglion cells (RGC), convey the perceptible information to the brain. The wavelength information of primary colors received by the cones are expected to have characteristic features in RGC responses before being perceived by the brain. Thus responses from the RGCs are recorded with multielectrode array (MEA) and analyzed to distinguish between light stimulus of different wavelengths. Two major types of neurons with opposite polarity were identified for each color and their spiking nature was studied. A spontaneous response was also detected for all the colors. Red, blue and green were uncorrelated with white light stimulus which clearly indicates wavelength information can be decoded from multineuronal recordings from RGCs. These information can be encoded in electric stimulus for prosthetic vision development.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773322","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}

In this paper, we introduce a novel design concept of MEMS inertial switch based on direct contact sensing method to eliminate the bouncing effect of the output signal. The switch was designed with a threshold value of 12 g and composed by a proof mass, suspended by six Z-shaped flexure beams. The fabrication was carried out on a SOI wafer with standard silicon micromachining. Two glass wafers were used to encapsulate the switch and establish a direct connection between movable electrode and the detection circuits. According to the centrifugal experiment results, the measured threshold value is around 11.8 g, which is in good agreement with the designed value. The comparison of contact behavior between direct and indirect contact switches was also carried out. The results showed that, the direct contact switch can eliminate the output signal bouncing effect especially when the applied acceleration signal was approximate to the threshold value of the switch.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115073362","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}
