In this paper, we investigate power efficiency aspects of a recently proposed adaptive nonuniform sampling. This sampling scheme minimizes the energy consumption of the sampling process, which is approximately proportional to sampling rate. The main characteristics of our method are that, first, sampling times do not need to be transmitted, since the receiver can compute them by using a function of previously taken samples, and second, only innovative samples are taken from the signal of interest, reducing the sampling rate and therefore the energy consumption. We call this scheme Time-Stampless Adaptive Nonuniform Sampling (TANS). TANS can be used in several scenarios, showing promising results in terms of energy savings, and can potentially enable the development of new applications that require continuous signals sensing, such as applications related to health monitoring, location tracking and entertainment.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"92 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":"133029518","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}

To meet these demanding specifications, we developed a simple functional model for an Elementary Motion Detector (EMD) circuit based on the common housefly's visual system. During the last two decades, several insect-based visual motion sensors have been designed and implemented on various robots, and considerable improvements have been made in terms of their mass, size and power consumption. The new lightweight visual motion sensor presented here generates 5 simultaneous neighboring measurements of the 1-D angular speed of a natural scene within a measurement range of more than one decade [25°/s; 350°/s]. Using a new sensory fusion method consisting in computing the median value of the 5 local motion units, we ended up with a more robust, more accurate and more frequently refreshed measurement of the 1-D angular speed.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"78 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":"133244710","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, despite linear dependence versus aqueous glucose concentration and potential high sensitivity, the selectivity to glucose remained an important issue. We then proposed a compound-specific complementary protocol that relies on the optical absorption coefficient. By using optical excitation at two π-shifted amplitude-modulated optical wavelengths, and sweeping the optical power of one source, we obtained linear dependence versus glucose and albumin, according to parameter-dependent coefficients. The combination of FS method with this new method at several sets of optical wavelengths then opens the door to selective and sensitive measurement of blood glucose level in a non-invasive and continuous manner.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"50 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":"131896230","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}

Both sides of a short length of PCF (∼3 mm) are spliced to conventional single mode fibers (SMF). The voids of the PCF are completely collapsed in the splice region, acting as mode splitter and combiner for the PCF modal interferometer. The bulk liquid sensitivity is about 70.2 nm/RIU (refractive index unit) based on the linear curve fit for refractive index ranging from 1.33 to 1.35.

The sensor can not only detect a chemical substance dissolved in water but also can determine the direction of its flow by using the shielding effect that appears between closely arranged working electrodes. Analysis of angular response characteristics of the sensor using an empirical model of the shielding effect has shown that at least four electrodes are required to determine the two-dimensional chemical flow direction. We have then fabricated a sensor probe with quadruple disk electrodes. Computational fluid dynamics simulations and sensor response measurements have shown that the proposed sensor responds to the local flow direction near the sensor surface. Therefore, the favorable probe design has turned out to be to arrange sensor electrodes on a round surface to avoid flow separation and backflow generation near the sensor electrodes.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"1 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":"115042940","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 sensor is a RLC resonant circuit consisting of an inductive coil connected in parallel to a thermistor, a varactor and a pH combination electrode. pH variation of the solution changes the voltage-dependent capacitance and shifts the resonant frequency of the sensor, while temperature change of the solution affects the resistance and changes the quality factor. The resonant frequency and quality factor of the sensor are tracked remotely by an interrogator coil coupled to the sensor coil. A temperature range of 25°C–60°C and pH over a 2–12 dynamic range can be measured simultaneously. With temperature compensation, the accuracy of the pH measurement is demonstrated to be 0.1 pH. The sensor overcomes the pH measurement error due to the temperature dependence of electrode based passive pH sensors.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"28 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":"115064622","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 geometry of such devices and the characteristic current flow in the deep n-wells strongly differ from those of structures used so far to characterize the piezo-Hall response. In contrast to standard planar Hall plates, homogeneous mechanical in-plane stress was found to cause a weak change in the magnetic sensitivity of the VHS. The paper presents the custom-made measurement setup and its detailed characterization as well as experimental results acquired using single VHS and coupled sensor systems comprising four VHS connected in parallel. The experimental results are supported by finite element simulations. It is concluded, that the low sensitivity change is due to the vertical current density changes induced by the applied mechanical stress.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"35 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":"117263731","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}
