Results of worm locomotion forces show that different parts of the worm's body exert forces on five individual pillars that were in contact with the worm throughout its movement. The fabrication process of the PDMS device is also explained in detail, along with the device casting procedures. The final section discusses the challenges and limitations tackled in this research, in particular during the fabrication process.","PeriodicalId":169983,"journal":{"name":"2016 IEEE International Conference on Semiconductor Electronics (ICSE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129611079","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}

There are few parameters need to be concerned in order to optimize the performance of SPR sensors such as film thicknesses, type of thin films and their configurations. In this study, we seek to determine the optimum thicknesses of hybrid thin films which consist of gold-graphene oxide layers for the enhancement of SPR sensor sensitivity. By using a theoretical approach, a WINSPALL 3.02 simulator had been used to investigate the effects of various thicknesses of hybrid configuration's thin films towards the excitation of surface plasmon polaritons (SPP). A layer of 3 nm protein was added to compare the maximum adsorption of the SPR sensor based on their configuration. It was found that the optimum thicknesses of gold and graphene oxide are 50 nm and 0.68 nm respectively for achieving best sensitivity. Thus, the sensitivity value for gold-GO thin films is higher than silver-GO which are 19.42 °/RIU and 5.45 °/RIU with FWHM = 2.28° and 0.64° respectively.","PeriodicalId":169983,"journal":{"name":"2016 IEEE International Conference on Semiconductor Electronics (ICSE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124550089","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}

An unit cell structure with reduced pillar height (hp/a)=0.5 and reduced radius (rp/a)=0.3 is simulated using Finite Element Method. The geometrical parameter is chosen to demonstrate a local resonance mechanism that allow the confinement of elastic energy at the interface between the solid and the fluid. In order to identify the energy distribution, we represent the eigenmode at high symmetry (point X) in the first Brillouin zone. The decreasing trend of frequency is also boosted with the increase of pillar height. From the total displacement, the energy is mostly located inside the pillar and only a small value of displacement is present in the substrate. The results from this study could be useful for microfluidic and lab on chip application. We believe that the integration of pillar based phononic crystal with microfluidic could become a powerful tool in the sensor and actuator application for chemical and biological application.","PeriodicalId":169983,"journal":{"name":"2016 IEEE International Conference on Semiconductor Electronics (ICSE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127256590","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 method has been proven to effectively reduce the SCE effect. In this research paper, the electrical characteristic of an 18 nm gate length SOI PMOSFET was analyzed based on the prediction of the International Technology Roadmap for Semiconductors (ITRS). The threshold voltage would be the key characteristic in this research. Four process parameters were used with two noise factors in order to conduct nine sets of experiments using the L9 orthogonal array Taguchi method. At the end of the experiment, the best setting that was predicted by the Taguchi method would be utilized for the purpose of verification.

The ratio of each species of argon and titanium was plotted and the trend of ionization mechanism was studied. We found that the Ar ion emission intensity increased with the discharge power indicating that the ionization of Ar increased with the discharge power.

Two microelectromechanical system (MEMS) cochlear biomodel design; Straight Bridge Beams (SBB) and Straight Bridge Beams with Centered Diaphragm (SBBCD), have been considered for ABM development. Comsol Multiphysics software is used to design ABM and simulate their performance in terms of resonant frequency and static capacitance. SBB MEMS cochlear biomodel was designed with the dimension of 0.5 μm thickness, 20 μm width and in a range of 275 μm to 7700 μm length.
