The purpose of the MLA magnifier is to generate a virtual image of a display, positioned within several centimeters from the eye, at optical infinity to minimize the optical disparity between the surrounding scenery and the image on the display. Our MLA magnifier is about 2 mm thick with a system focal length of 5 mm and a total thickness of around 7 mm (excluding the thickness of the display) in non-folded optics configuration, which is much more compact in comparison to other popular NEDs such as Google Glass or Recon Instrument's Snow goggles having folded optics.","PeriodicalId":337894,"journal":{"name":"2015 28th IEEE International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122123660","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}

As the cells in a population (e.g., tumor) is inevitably heterogeneous, a technique to measure the transport activities at a single-cell level is needed. When adherent cells were cultured on the microwells with ~10 μm diameter, they spread over the opening to form the closed picoliter space. Thus, molecules exported from cells accumulate in such a space and be detected by fluorescence imaging. In this report, we show that, by employing horizontal microwell design, materials exported from the cell membrane can be visualized without overlapping with the cell, increasing the S/N ratio of the fluorescence signal. Efflux of the cancer drug transported by the multidrug resistance protein was detected.","PeriodicalId":337894,"journal":{"name":"2015 28th IEEE International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117332519","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 based on a silicon-micromachined spacer that is mounted on top of a conventional CNC-machined metallic cavity to functionalize the resonator's capacitance. For the first time, it is demonstrated that low-frequency resonators with micrometer-scale gaps (10s of microns), relatively large Q-factor (459-505) and tunable response (18.5%) can be constructed without the need for post-fabrication tuning. To demonstrate these benefits, a resonator assembly was designed, built and experimentally tested at the UHF band and for a frequency tuning range between 1424-1711 MHz.","PeriodicalId":337894,"journal":{"name":"2015 28th IEEE International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122990222","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 repetitive uniaxial tensile tests are done to characterize its mechanical behavior and the water vapor transmission rate is measured to evaluate its barrier property. The experimental data are in accordance with the composite material theory. A novel approach of facilitating the diffusion and penetration of parylene coatings into PDMS using in-situ heated deposition is presented. The parylene depth profiling in PDMS and 180° peel tests demonstrate that parylene deposition at elevated temperatures shows enhanced pore sealing capability. A theoretical model is proposed, featuring an infinitely long cylindrical PDMS pore model, free molecular flow and time-varying pore geometry during the deposition. There is only one unknown parameter in the model: the PDMS pore diameter. By fitting the numerical solutions of the theoretical model to the parylene depth profiling curves, the PDMS pore diameter is estimated to be ~6.02nm.","PeriodicalId":337894,"journal":{"name":"2015 28th IEEE International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129043022","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}
