The paddle is designed to work with torsional vibrating mode to improve the sensitivity. To simplify the fabrication, low-stressed SiNx with 5 um in thickness is used as the paddle. A positive-feedback circuitry is used to compensate the energy loss by the big damp in liquid, so that the SNR and the Q-factor of the paddle can be improved obviously. Characteristics experiments show that the Q-factor of the paddle in alcohol is enhanced from 2.65 to 24.55, and the torsional resonant frequency and the Q-factor of the paddle decrease with the density and the viscosity of the mixture solution respectively.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116619408","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, a novel class of nonconformal Fermat-like spiral multi-port microantennas for next-generation remote sensing applications is presented. The antenna modeling is carried out by using a computationally enhanced locally conformal finite-difference time-domain full-wave procedure. In this way, the circuital characteristics and radiation properties of the device are investigated accurately. The sensor reconfigurability, in terms of frequency of operation and radiation efficiency, is technically achieved by a suitable solid-state tuning circuitry adopted to dinamically change the feeding/loading conditions at the antenna input ports.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116867672","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 phononic crystal consists of a metal plate with a periodic array of holes. Ultrasound propagates in a way that the incidence direction of sound is perpendicular to the plate. A characteristic transmission peak has been found to strongly depend on liquid sound velocity. The respective peak maximum frequency serves as measure for liquid composition. Numerical calculations based on FDTD and FEA reveal more insides to the propagation characteristics, in particular the presence of specific plate modes.

The problem is that the body can easily obstruct the transmission of low-power radio signals, thereby significantly reducing the success rate of data communication from the sensor nodes to the sinks. In this paper, we propose a novel relay node placement scheme for preserving network connectivity, and therefore enhance the success rate of data communication. We empirically evaluate our approach using a wearable sensor platform to show the improvements in packet success rates. Our experiments show that in most cases the average improvement can reach 34.74 %.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128318369","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}

Some of the major benefits that will be discussed include the (1) Higher vertical resolution sounding in all-weather conditions, (2) Increased precision and accuracy of the products due to decreased cross-talk and to a better isolation of signals, (3) Reduced sensitivity to background information due to increased information content, (4) Extended spatial coverage, (5) Hydrometeors profiling in both liquid and frozen phases, (6) Numerical Weather Prediction (NWP) model forecast improvement, (7) Reduction in the uncertainties of the spectroscopic parameters in the microwave spectrum (line coupling, temperature dependence, line strengths and widths) and (8) Better physical modeling of absorption and scattering by atmospheric and surface parameters.
