    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low noise; InAs AlSb; metamorphic; low power; high frequency; high electron mobility transistor HEMT ; cryogenic; ion implantation;

    Sammanfattning : The InAs/AlSb high electron mobility transistor (HEMT) is an emerging microwave device technology for ultra-low power and low noise applications. Due to the low bandgap (0. LÄS MER

  3. 12. Micro-scale Platforms for Investigations of Biological Structures

    Författare :Anna Kim; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microfabrication; non-ionic surfactants; single-cell viability; hydrodynamic flow confinement; cell-to-cell connections; SU-8; Teflon AF; cell protrusions; free-standing probes; millimeter-waves;

    Sammanfattning : This thesis describes the development of innovative micro-scale platforms as a means to address the current challenges within the field of cell biology, and to provide an interface between miniaturized analytical technology and experimental systems for the life sciences. The work includes an analytical platform for rapid assessment of the viability of adherent single cells; a surface patterning strategy for investigations of cell-to-cell communication via protrusions; a versatile microfluidic probe in SU-8 hard-polymer, and a microfabricated millimeter-wave measurement system for the identification and characterization of niosome (non-ionic surfactant vesicle) constituents, which is operated in a label-free, non-invasive manner.

  4. 13. The impression technique for assessment of tissue oedema : instrumentation, evaluation and applications

    Författare :Olof Lindahl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICINE; MEDICIN; Medical Engineering for Healthcare;

    Sammanfattning : An instrument for clinical noninvasive assessment of tissue oedema based on an impression method was developed. The method measures and evaluates the decaying force, due to translocation of tissue fluid, during mechanical compression of any site of tissue. We applied the impression method on physical models, animal models, and patients. LÄS MER

  7. 15. Modular textile-enabled bioimpedance system for personalized health monitoring applications

    Författare :Javier Ferreira; Fernando Seoane; Kaj Lindecrantz; Orjan Grottem Martinsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; personal healthcare system; electrical bioimpedance; wearable sensors; pervasive monitoring; portable monitoring; body composition; chronic kidney disease; wireless sensor; ubiquitous; instrumentation; Technology and Health; Teknik och hälsa;

    Sammanfattning : A growing number of factors, including costs, technological advancements, ageing populations, and medical errors, are leading industrialized countries to invest in research on alternative solutions to improve their health-care systems and increase patients’ quality of life. Personal health systems (PHS) examplify the use of information and communication technologies that enable a paradigm shift from the traditional hospital-centered healthcare delivery model toward a preventive and person-centered approach.
