SU-8/ITO microcantilever has been fabricated to electromechanically extract the piezoresistive property of ITO which has been considered for simulation. The simulated device consists of a circular membrane coated with receptor layer suspended by inverse trapezoidal flexures with embedded piezoresistors. Surface stress induced on the membrane due to target binding is transduced as a uniaxial stress in the flexures which is then sensed using piezoresistors. A conventional polymer U-shaped piezoresistive cantilever is also designed and simulated for comparison. The surface stress sensitivity of HMF-NM sensor is extracted as 4.01 ppm/[mN/m] which is more than 20 times that of a conventional cantilever.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127628109","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 bearing clearance can be determined based on the energy spectrum of the rotation vibration by the application of neural networks. Experimental investigations are performed using two double-row self-aligning ball bearings and vibration sensors in order to examine this assumption. The bearing vibrations are recorded at different clearances and rotation frequencies and analyzed. The developed system can be used for monitoring or prediction of clearance during service.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127708718","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}

Therefore, this paper proposes an indoor human location recognition method that uses the vibration signals captured by floor-mounted acceleration sensors. This method eliminates the carrying of devices while protecting personal dignity. Experiments that use 3 acceleration sensors placed on a wooden floor show that the location of a person can be recognized within 2 m from a sensor module with more than 70 % accuracy. An enhanced version offers accuracy of more than 85 %.

The salient aspects of processing such a composite is summarized. This involved preparing samples by using the spin coating technique. Samples of the composite mixture are spin coated on silver-coated glass slides at 2000 rpm for 10s to give a layer thickness of 100μm.

The U.S. Food and Drug Administration (FDA) has also been concerned about the unknown rate of repeat and prolonged use of ultrasound detectors. Fetal electrocardiogram (fECG) and HR monitoring devices based on bio-potential acquisition have been developed; however, they are bulky and intrusive, thus not widely accepted. Here, we present innovative non-contact electrode ECG sensors on a small unobtrusive patch which could be attached to the abdomen, or inside garment, incorporated with Bluetooth low energy (BLE) wireless communication, to transfer the acquired data to a smartphone. An Android app was developed to extract the mixed maternal/fetal ECG (f/mECG) signals. In this paper, we demonstrate a simple and robust scheme to provide accurate 24/7 monitoring of f/mHR, with the potential to expand to f/mECG monitoring in the home setting.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132103470","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 propose sidewall coverage of PZT and Pt film while carrying out deep silicon etch in DRIE to avoid possible exposure of these contaminating materials to the tool. With this process, we have fabricated a gyroscope structure with electrostatic comb drive actuation and piezoelectric sensing.

Results indicate that MoO3 micrograss encapsulated ZnO microcube composite has higher sensitivity and selectivity towards methanol compare to its individual component.

It has been shown that this pathology is associated with an increase of ammonia concentration in breath. Measuring it with a handheld system is a simple way for a noninvasive and early diagnostic. The idea of this paper is to measure the concentration of ammonia in a concentration range of human breath (500 ppb-2100 ppb) with humidity using a network of 11 different nanocomposite sensors. To overcome sensor weaknesses (sensor drift and sensitivity to humidity), the electronic nose principles are applied. Polyaniline-based nanocomposites with titanium dioxide, chitosan and carbon nanotubes are used to provide different sensitivities and response times and thus associate a single pattern to a concentration range. Several classifiers are then investigated and recursive feature elimination algorithm are used to select the most relevant features and sensors while improving the measurement accuracy. Diagnosis accuracy reaches 91% with the combination of feature selection and Support Vector Machine algorithm.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132466311","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}

Proposed SDCF adopts a context-aware forwarding strategy to ensure higher delivery reliability with reduced delay. The overall packet loss is much lower for SDCF as the design involves adaptive data forwarding technique coupled with data fusion. The effectiveness of the proposed routing mechanism has been established by a simulation based comparative analysis with AODV routing protocol.","PeriodicalId":405874,"journal":{"name":"2018 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133971757","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}
