In this paper, we propose a new scheme, i.e. open-top SU-8 microfluidic channel, to generate micropatterns of extracellular matrix (ECM) proteins to guide and control the neuron outgrowth in preferred directions and at designed positions by confinement in a microfluidic system. The open-top SU-8 microfluidic channel, which requires only a small volume (~0.5µl) of laminin solution to fill the two tanks and microchannel, is 20µm thick and 10µm wide. The culturing of retinal ganglion cells (RGCs) was performed using injured goldfish. The experimental results verify that the open-top SU-8 microfluidic channel is not only workable but also effective for neural guidance.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251267","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}

MEMS have been extensively used as micro-scale high-quality oscillators, communication resonators, microphones, amplifiers and other micro-oscillators. In this investigation, mathematical model of a micro-mechanical resonator is developed subject to a full nonlinear model. The governing equation is a nonlinear parametric and hence, the stability of the system depends on the value of its parameters. The output signal of MEMS is not reliable when it is operating in a saturated or in an instable region. From a design viewpoint, a stability chart is needed to indicate the relationship between the parameters to determine when the system is stable, periodic, or unstable. Nondimensional and linearized model of the MEMS is studied and a stability diagram is developed for the system.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115733204","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}

Of the particular interests to this study is the application of the Capacitive Micro Strain Gauge in on-a-chip systems for biomedical and industrial health monitoring. A combination of analytical and numerical approaches is presented to extract strain components from capacitance. The studies show that capacitance is affected by the size of dielectric. It is also explored to be a function of normal components of strain while shear components have no effect on capacitance. A suitable approach is presented to shift the actual capacitance to the theoretical capacitance.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132492761","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}

Artificial self-assembly derives its principles from nature and its processes, and uses this understanding to design nanoscale devices with predefined function. However, complex forms of organized matter cannot be synthesized bond-by-bond. Rather, a new type of synthesis based on noncovalent forces is necessary to generate functional entities from the bottom up. This growing field of the chemical sciences challenges much of the basic premises of conventional Woodwardian chemistry: The conceptualization of an organized state of matter requires in-depth understanding not only of chemical reactivity but also of noncovalent forces necessary to translate chemical information into functional superstructures.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132019522","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 array is designed to meet the requirements of satellite-based infrared imaging and detection applications, including cloud and earth surface temperature monitoring and forest fire monitoring. Its design makes it also suitable for terrestrial spectrometric and moderate speed imaging applications. The array consists of three parallel lines of 512 pixels on a 39 µm pitch. Each pixel includes both active and reference detectors to reduce pixel to pixel offset variation, eliminate common mode bias noise, and provide increased immunity to die temperature drift. The thin films making up the active detector structure are designed to provide high and uniform infrared absorption between 8.3 and 13 µm. The pixels are fabricated monolithically over a custom CMOS readout integrated circuit (ROIC) using a surface micromachined post-processing approach. The advanced ROIC integrates the signals of all pixels in parallel using switched capacitor correlated double sampling integrators and performs on-chip analog to digital conversion. Despite the small pixel size the projected thermal resolution over the 8-12 µm spectral band for f/1 optics is below 50 mK. In this paper we will describe the detector array design and present preliminary test results.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125268076","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}
