However, the application of optical fibers to all aircraft systems, in particular fly-by-light, is of significant interest. In this work, an integrated engine instrumentation and monitoring system based on optical fiber Bragg grating sensors is proposed. Engine instrumentation and monitoring requires a number of different sensors, including temperature, pressure, RPM, and vibration. All four of these measurands can be monitored using FBGs, multiplexed together using the same interrogation system. Results for all of these measurands are presented, including proposed transducers for both pressure and vibration. In addition, the overall optical fiber monitoring system is proposed.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128300775","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 required area to micromachine the air pit for the μHP of a single sensor is several times more than the actual area required by the sensor itself. The feasibility of implementing low power and ultra dense gaseous sensor array is investigated by developing a new μHP structure using recessed silica aerogel. In comparison with the conventional μHP structure, the recessed aerogel not only has decreased the utilized area of the chip almost ten folds (181 × 181 μm2 vs. 573 × 573 μm2) to maintain a temperature of 360 °C but also has decreased the power consumed by each μHP more than two folds (1 mW vs. 2:1 mW). As the number of sensors increases in a sensor array, the saved area of the chip increases quadratic by using the new structure. Moreover, the power consumed by the new designed structure reduces drastically.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134007913","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}

By employing the concepts of Compressive Sensing (CS) theory it is possible to reconstruct a sparse signal with a certain number of random linear measurements, which is much less than the number of measurements necessary in conventional signal reconstruction techniques. In this study, we built an energy dissipation model to quantitatively compare the energy dissipation characteristics of CS and conventional signal processing techniques. This model is used to construct a Linear Programming (LP) framework that jointly captures the energy costs for computing and communication both for CS based techniques and conventional techniques. It is observed that CS prolongs the network lifetime for sparse signals.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122419346","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}

However, limited power storage, which requires battery replacement, remains a major technical challenge that hinders the deployment of wireless sensor networks, despite the many advantages of using them for structure monitoring. Thus it is very attractive for wireless sensor nodes to be able to harvest energy from the ambient environment to provide power for the sensing, processing, and communications operations. In the paper, we studied the ambient energy harvesting problem of wireless sensors for bridge monitoring and how to achieve complete self-sustainability. The available energy resources were investigated for the bridge monitoring application. A wireless sensor system was implemented and test results on its energy consumption profiles were provided. With careful budgeting it is feasible to achieve complete self-sustainability for some applications with ambient energy harvesting.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117003676","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 applications are not limited to solely monitoring but can be extended to behavioral recognition. This can be of great value with the elderly as it can allow anomalous behavior to be detected and corrective actions taken accordingly. This paper details the installation and configuration of unobtrusive sensors in an elderly person's house - a smart home in the making - in a small city in New Zealand. The overall system is envisaged to use machine learning to analyze the data generated by the sensor nodes.

The re-designed sensor head detects electromagnetic changes caused by the presence of ferromagnetic tags attached to target pathological and bioterrorism agents (zoonotic microorganisms) both in liquid or gaseous specimens. The system circuits then transform the measured magnetic effects into digital data used to count the number and type of organisms present. The advanced one piece wiring inductor in the conical shape acts as the sensor head. Most important is that the wire geometry achieves ultra-uniformity of the magnetic field magnitude, which ensures a high level of the system accuracy since the randomly located particles will produce nearly the same magnetic flux change over the surface of the sample container. A 3D model is used to simulate organisms tagged with iron nanoparticles being sensed in the system, and the results indicate a maximum difference in effect of 7% when a single biological is moved to various locations across the sensing container surface.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124275840","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 particular, the electromechanical impedance has been used for identifying local damaged regions by monitoring the changes in structural mechanical properties, which are coupled with the electrical impedance of a PZT patch. In the guided wave propagation, one PZT patch acting as an actuator launches an elastic wave through the structure, which is can be measured by another PZT patch. The integration approach of these two methodologies is then straightforward because the same piezoelectric patch can be used for both methods. This integration approach is experimentally validated in this work by developing a reused and “multi-mode” sensing system for damage detection of concrete structures.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116334739","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 result is a non-TDMA, distributed, digital single wire bus protocol that allows sensors to communicate with each other simultaneously and asynchronously without requiring a master node. At a minimum, the enhancements double the capacity in terms of the number of the nodes on the bus for a fixed error rate, and improve by four times the data rate compared to the previous scheme.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122039992","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}

We show that a FBG sensor can be used effectively as an embedded in-ground acoustic sensor, sensitive enough to detect the acoustic emissions associated with walking on a concrete surface. Also, the FBG can be used as an in-ground pressure switch for intrusion detection through temporary flooring materials, such as tiles and wooden laminate. In addition, we verify the use of FBGs as in-fence perimeter breach detectors. Finally, we show how an FBG can be used as a reed switch for use in intrusion detection systems for doors and windows. The combination of the different intrusion detection techniques illustrate the versatility of FBGs in security applications, showing this single technology can be used to form a complete intrusion detection system for homeland security.
