The experimental results indicate that the sensor is capable of detecting Ca and Mg ions down to 1 ppm with a linear detection range from 10 to 50 ppm.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127516779","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}

At first, an improved complete ensemble empirical mode decomposition (Improved CEEMD) is used to decompose the original signal into a series of stationary modes; then the distinct sub-series are clustered based on the sample entropy, and extreme learning machine (ELM) based model is used to train the sub-series; finally, the desired results can be obtained after de-noise and compensation. To verify the method, MEMS gyroscope CRG20 has been chosen for an hour test, and the experiment shows that zero bias drift reduced from 0.0706°/s to 0.0706°/s($1-sigma )$ within temperature range of − 40° C to 70° C.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129332290","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}

It is found that the tri-gate nMOSFET simulated at high Vds has shown better performance compared to planar nMOSFET simulated at low Vds. As the Rsd is reduced, the drain current of both planar and tri-gate devices increases. The on-current to off-current (${text{I}}_{text{on}})/{text{I}}_{text{off}}$) ratio of the devices also increases as the Rsd reduced. Tri-gate nMOSFET shows significant improvement as the Ion/Ioff ratio is $10^{3}$ higher than the planar nMOSFET device.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134598381","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 islands' length, width and height follow the Arrhenius relation with activation energies ranging from 0.4 – 1.6 eV.

This paper presents the fundamental development stage of graphene-based piezoresistive intracranial pressure sensor, i.e., to determine its diaphragm design, which is made of polydimethylsiloxane polymer. Different thicknesses of a square diaphragm were simulated using COMSOL Multiphysics. The Parametric Sweep function was used to simultaneously simulate the changes of two parameters, namely diaphragm thickness and operating pressure. It was found that the thin diaphragm is more susceptible to deform due to the rapid geometry changes and the differences in modulus of elasticity of the materials used in the design. Meanwhile, the stress experienced by the diaphragm degraded with the increase in thickness. However, a slight modification in designing and positioning the piezoresistors would make the sensor's performance on par with those of thin diaphragm. Hence, by selecting the right thickness and shape of polydimethylsiloxane diaphragm, it will serve as a good platform in developing the graphene-based piezoresistive intracranial pressure sensor.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127188181","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}
