The sensor unit is composed of a polyvinylidene fluoride (PVDF) layer sandwiched in between topand bottom-electrode layers which are made of conductive silver ink. The sensing mechanism bases on the pyroelectricity of the PVDF layer. The aforesaid sandwiched sensor units are sprayed simultaneously on a flexible polyimide (PI) substrate layer by layer to form a sensor key-panel. The resembling print screen process is very low-cost. The prototype demonstrates that it is sensitive to human fingers, and therefore one of its applications is becoming for a flexible non-contact proximity key-panel for the user interface of instruments or machines. It may also be applied to proximity sensing or thermal radiation sensing. The proposed flexible proximity key-panel is also suitable for massive roll-to-roll process.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130409648","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 switches operate at both room temperature and high temperature up to T 500oC in ambient air with enhanced control over the distributed electrostatic actuation force, and also enable recovery from stiction at contact. We have experimentally demonstrated multiple switching cycles of these nanomechanical switches with different actuation control schemes, and active release from stiction by exploiting a repulsive mechanism. In combination with modeling of cantilever deflection, the experiments help reveal the coupled electromechanical behavior of the device when making contact during switching operations, and suggest possible correlation between the switch degradation observed over cycles and the elastic deformation of nanocantilevers.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117212098","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}

A hydrodynamic analysis was performed to elucidate the underlying interaction between ciliated structures and the induced flow fields. To fabricate ciliated structures, the micromachining method together with a casting process was employed. These ciliated structures were actuated in a homogeneous magnetic field generated by an in-house magnetic coil system for various beating cycles inside a microchannel. Three representative signal waveforms were created to mimic the beating nature of cilia for different flow actuating functions, such as micromixing and micropropulsion. To investigate the flow structures of induced flow fields quantitatively, a numerical modeling method using Fluid-Structure-Interaction module was performed. In addition, a micro-particle image velocimetry (μPIV) experiment was conducted to characterize the nonreciprocal movement of ciliated structures for the quantification of hydrodynamic efficiency. By means of the presented analysis paradigms, a new flow manipulation strategy will be suggested to transport/agitate flows efficiently in microfluidics.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117253470","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}

Human motion consists of burst of low frequency vibrational kinetic energy. The high acceleration burst is usually 1. 5 to 2 g when the foot strikes the ground and an ionic polymer metallic composite (IPMC) can be used to harvest this energy via two methods. The first method is via the bending of the IPMC causing the mobile cations to move and produces an output voltage pulse, hence capacitive transduction. Secondly, the IPMC in a beam form that resonate at the low vibration frequency due to its relatively low Young's modulus can scavenge additional secondary energy via external electromagnetic transduction to supplement the primary harvested energy via the IPMC capacitive transduction.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125632424","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 copper nanowire arrays were fabricated using electrochemical deposition in 0.2 M CuSO4 by different potential modes including direct current (DC) and pulse. The nanostructure, morphology, chemical composition and phase of copper nanowire arrays were examined by scanning electron microscopy and grazing incidence X-ray diffraction. The results indicated that the copper nanowire arrays deposited by pulse mode revealed high aspect ratio despite high potential while that at higher DC potential was rather short due to the hydrogen generation in reduction reaction. The short duty cycle of 50% in pulse deposition can release the produced hydrogen for good nanowires formation.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133868468","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 work, targeting efficiency was quantitatively characterized using silica particles functionalized with EpCAM antibodies and EpCAM-expressing BT-20 breast cancer cells. The effects of incubation time and particle concentration on the number of functionalized particles bound to target cells were experimentally investigated. The number of bound particles was found to increase with particle concentration, but not necessarily with incubation time. While particle desorption and cellular loss of binding affinity in time seem to be negligible, cell-particle-cell interaction was identified as the limiting mechanism for the number of particles bound to target cells. The current findings suggest that separation of a bound particle from a cell may be detrimental to cellular binding affinity.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122706000","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}
