  1. 6. A Microstrip Antenna for Medical Application : Tissues Detection

    University essay from Högskolan i Gävle/Elektronik

    Author : ZhenYun Xie; [2017]
    Keywords : Microstrip antenna; Tissues detection;

    Abstract : The purpose of this thesis is going to design a microstrip antenna that can detect the different tissue, according to this clue, we suppose that it can be used in medical application, for example to detect the breast tumor. Our research and guess are based on the different electrical properties of the tissue. READ MORE

  3. 7. A Technical Evaluation of Capacitive Level Sensors for use in Hemodialysis Machines on Chambers Filled with Dielectric Liquids

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Viktor Stevander; Viktor Petersson; [2016]
    Keywords : comb-finger; parallel fingers; capacitive sensor; Electrical engineering; Electric measurement; hemodialysis; dialysis machine; Technology and Engineering;

    Abstract : A series of tests were performed to explore the limits of two capacitive level sensors using the principle of parallel finger layout (sometimes called comb fingers) for sensing. The goal was to present a decision basis for Baxter to use when choosing a sensor to implement in their next generation hemodialysis machine. READ MORE

  4. 8. Microwave phantoms for Craniotomy and bone defect monitoring

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Velander Jacob; [2015]
    Keywords : agar; BMP; body morphogenetic protein; bone implant; brain phantom; craniosynostosis; craniotomy; cube phantom; phantom; re-growing bone; skin phantom; skull phantom; tissue;

    Abstract : To facilitate examination for osteogenesis and follow up after craniotomy similar head models called phantoms are made. The head phantom should emulate the tissues from a real head. This requires that the realistic head phantom have the same electrical properties as relative permittivity (dielectric constant) and conductivity. READ MORE

  5. 9. Effect of Heat Treatment on Morphology and Dielectric Properties of Polyethylene

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Md Tanbhir Hoq; [2014]
    Keywords : Polyethylene; Morphology; Annealing; Sample Swelling; Dielectric Spectroscopy; Differential Scanning Calorimetry; Crystallinity; heat Treatment; Power Cable; High Voltage; Permittivity; Polyeten; Morfologi; Anlöpning; Svällning; Dielektrisk spektroskopi; Differentiell svepkalorimetri; Kristallinitet; Värmebehandling; Kraftkabel; Högspänning; Permittivitet;

    Abstract : Polyethylene is used extensively as an insulating material in high voltage power cables, it is therefore important to understand the behaviour of polyethylene under different conditions. This is a study regarding the relation of heat treatment and the effect of morphological changes on the dielectric properties of polyethylene samples. READ MORE

  6. 10. MEASUREMENT OF DIELECTRIC CONSTANT FOR WATER AND ITS TEMPERATURE DEPENDENCE AT 0 AND 86ºC

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Sergio Apicella Fernández; [2014]
    Keywords : ;

    Abstract : The dielectric properties determine the electrical characteristics of materials. These properties are important for understanding the behavior of materials and how they can interact with each other. READ MORE
