Non-integer quantum steps were modeled using multi-branch growth of nanowires at sub-threshold voltages. As each branch or fractional branch forms, the device conductance increases by an integral or fractional step correspondingly. In gated devices, the gate voltage (both +/- polarities) turned off devices eliminating the need for bipolar drain-source voltages. The gated memristors showed 106 On/Off current ratios with 10 mV/decade slope. The nanowires were also imaged using contact-mode AFM that clearly showed wires protruding out-of the devices plane. A computational model using Matlab was developed to qualitatively model the quantized conductance and gate field effects. Since nanowires can be dissolved/formed (i.e., programmed) electronically, their presence at the surface can be used to program the sensing mechanisms in these devices.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"12 1","pages":"819-822"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89293564","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}

Due to the advantages in size and response time, antimony and Ag/AgCl electrodes were used as the working and reference electrodes of the sensor respectively. Three prototypes were designed and fabricated. The first two sensors adopted the separated electrodes with different size, while the last sensor adopted the integrated ones, which was the smallest with the length of 5mm and diameter of 6.7mm. The linearity, accuracy, response time and temperature drift of three sensors were measured to assess their performance. The experimental results showed that when the temperature was fixed, the correlation coefficients were above 0.99, the error rates with buffer solution were below 3% and the response time from the neuter to strong acid was below 5 seconds. Besides, the error rate caused by the temperature drift could be reduced to the range of 1% with the compensation. Due to the advantage in size and performance, the last sensor could be integrated into the capsule endoscope.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"14 1","pages":"339-342"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85315602","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}

Recent research work has been dedicated to demonstrate the feasibility of detecting ice accretion events on transmission lines by means of autonomous sensor systems. In this article we present a study of different icing scenarios and environmental influences for a capacitive icing sensor. We develop a model to predict the sensor response for typical ice loads. The model is also used to quantify the sensor cross-sensitivities with respect to environmental conditions (e.g. water films, condensation layers etc.). The model is validated by means of experimental data obtained during laboratory investigations.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"369 1","pages":"2042-2045"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76889211","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 problem is formulated as a potential game in which each player computes a local utility function defined by the conditional mutual information. A new approximation method is proposed for computing the conditional mutual information when the target states are represented using a particle filter to handle a non-linear system with non-Gaussian noise. This method approximates the conditional entropy of an agent conditioned on other agents sensing decision by sampling the other agents measurements from a particle filter. This computational method makes it possible to apply the potential game approach to non-linear/non-Gaussian problems with a large number of the measurements. We performed simulations for localization and tracking of a target with mobile/deployed sensor networks.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"17 1","pages":"1256-1259"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77020546","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 paper demonstrates that an effective ultrasonic gesture-sensing system can be implemented using commercially-available MEMS microphones. The system works by sending ultrasonic pulses with a center frequency of 40kHz using a piezo-electric transmitter and detecting the resulting echoes using an array of seven microphones. The microphones are mounted at a pitch of 4.3mm to enable beamforming with acceptable grating-lobe levels. The received signals are digitized using successive approximation ADCs, after which a B-mode image is constructed in an FPGA and object locations are estimated using peak detection. Within a range of 5cm to 100cm, object locations can be detected with a resolution of 1.67cm and 1.5°. Based on the detected object locations, a simple gesture-recognition algorithm implemented in software can accurately detect horizontal swiping gestures.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"75 1","pages":"90-93"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74982556","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 sensors have been mounted to an easy to put on headband and the use of three sensors eliminates the need for additional facial electrodes. The EPS is based on an active electrode with an ultra high input impedance of ~50GΩ and ~7pF. The sensors capacitively couple to the skin through an inert insulating layer, thus no skin preparation or conductive gels are required. There is no DC drift and the EPS does not suffer any negative effects due to variations in skin resistance caused by sweating. A typical EOG signal is shown with no visible crosstalk.

The device consists of a movable shuttle supported by slender flexures, integrated thermal displacement sensors and comb-drive actuators controlled with a customized circuitry. The operation principle is simple but subtle: as the device applies loads on a sample, any shuttle displacement which would typically be incurred in conventional systems, is immediately nullified through an electrostatic force generated by the combs. The system allows the forces to be transduced directly. And, more importantly, thanks to the control algorithm, the range and precision of the applied forces become independent of both the mechanical device parameters and sample compliance. Hence, the number of necessary calibration steps is reduced significantly whilst the measurement range is substantially increased.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"26 1","pages":"1745-1748"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74765715","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}
