NGs are known by their simple structure and excellent piezoelectric performance after polarization. However, the polarization is very long and unsafe. In order to avoid that, the proposed solution was to dope multiwalled carbon nanotubes (MWCNTs) for better distribution of piezoelectric nanoparticles. In this work, piezoelectric nanocomposite generators were prepared using solution mixing and mold casting. A comparative study was performed to investigate the impact of MWCNTs via morphological and mechanical testing. Both nanogenerators shows good performance due to high uniformity of nanoparticle distribution within the polymer matrix showing the efficiency of the adapted fabrication process. In addition, doping multiwalled carbon nanotube (MWCNTs) within the piezoelectric nanocomposite leads to increase the output voltage by about 20% comparing to the NG without carbon nanotube (CNTs) which corresponds to 6.6 V and a power of ~37.87 μW at a load resistance of about 660 kΩ due to the enhanced distribution of the nanoparticle and better electro-mechanical coupling.","PeriodicalId":438378,"journal":{"name":"2019 5th International Conference on Nanotechnology for Instrumentation and Measurement (NanofIM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130709465","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 determination of metal hardness is vital in these processes. Thus, the need for non-destructive metallic material hardness analyzers is increasing.In this paper, we propose to design, test and evaluate an inductive sensor system, which can analyze the hardness level of metallic materials in relation to the lift-off between metal surface and coil sensor. In this work, we have used an eddy current inductive sensor, which can differentiate between unhardened and hardened metal surface on the basis of magnetic properties like ‘permeability’. The eddy current sensor was designed and tested with an impedance analyzer in the frequency range of 4 kHz to 4 MHz over the metallic surface and the inductance results were compared to the Dodd and Deeds model simulation on MATLAB. The system evaluation shows the different permeability values for unhardened and hardened metal surfaces thus, Dodd and Deeds model together with non-contact inductive sensor system design can be used for analysing hardness level of ferromagnetic materials.","PeriodicalId":438378,"journal":{"name":"2019 5th International Conference on Nanotechnology for Instrumentation and Measurement (NanofIM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123457785","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}

Several approaches such as optical, chromatography and electrochemical techniques have been followed to detect nitrite. Electrochemical sensors are attractive because of their ease of preparation, low cost, fast response time and on/field measurement ability. We introduce the use of polyaniline polymer and carbon screen-printed electrode for detection of nitrite. Polyaniline is a conducting polymer with high environmental stability and conducting properties. The working electrode was electrochemically polymerized in different acid solutions. Here we show the effect of the different acids on the electro polymerization of aniline towards the electrochemical sensing properties for nitrite. It was investigated that polymerization in sulphuric acid was found to achieve the best sensitivity towards nitrite detection. The effect of number of scans and scan rate of electropolymerization had a significant effect on the detection of nitrite.","PeriodicalId":438378,"journal":{"name":"2019 5th International Conference on Nanotechnology for Instrumentation and Measurement (NanofIM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116899512","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 power transmission can be realized by using a couple of coils placed in proximity of each other. These coils may differ in their materials, technology, and geometries. In this paper, an investigation of different flexible coils geometries has been carried out. In fact, we investigate circular, square hexagonal and octagonal shapes with similar design parameters such as an internal radius of 2.4 cm, an external radius of 4 cm and six turns. The coils comparison is based on the measurement of the self-inductances and quality factors of the coils in different situations, such as number of used coils sides, damping and ideal states. The results show a similar behavior of the singular and dual-sided coils. The highest coil’s quality factor was in the case of a circular coil shape, whereas the highest self-inductance was in the case of a square coil shape. The coil with circular shape shows the lowest self-inductance and quality factor variation in the case of maximum coil damping.","PeriodicalId":438378,"journal":{"name":"2019 5th International Conference on Nanotechnology for Instrumentation and Measurement (NanofIM)","volume":"45 22","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120882897","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 propose two FMG detection systems with minimal number of FSR sensors (four and eight) for American sign language recognition based on raw FMG with implementation of Extreme learning machine (ELM) for evaluating the accuracy of nine ALS alphabet recognition. The first feasibility test for ALS sign detection with FMG systems was tested with one subject with an ELM accuracy of 78% with four sensors and 97.90 % with eight and the minimal efficient sensor number was preliminary investigated in the second band.
